The Basics of Simplifying Radicals

As a math student, you need to have the right understanding of radicals and relevant terms to achieve your academic success. What does the process of simplifying radicals involve? Basically, it’s all about manipulating specific radical expressions into their alternate or simpler forms. You can call it the process of simplifying algebraic expressions applied to radicals. Don’t forget that radicals are those exponential numbers where exponents are fractions. If your homework includes simplifying radicals, make sure that you know how to complete it properly, or think about the services offered by skilled freelancers. Look for their contact details online to benefit from affordable and quality offers.

How should you simplify radical expressions? First, you should learn that radical expressions always include a square, cube, or higher root. It’s interesting that they can describe the same number, even if they look quite different. What can you do to simplify this task? The most effective solution when simplifying radicals is to determine the right canonical form for given expressions. If you see 2 expressions in their canonical forms, but they still look different, this means that they are unequal. Keep in mind that these forms for radical expressions must meet certain requirements, such as the following:

  • Not using fraction exponents.
  • Avoiding fractions in radicals.
  • Not multiplying radicals by radicals.
  • Avoiding radicals in denominators.
  • Having only square-free terms under radicals.

Is there any practice use for that? How to deal with simplifying radicals? The good news is that you can try multiple choice exams to succeed. For example, if a given math problem is solved, but the answer you have doesn’t match any multiple choices, you need to simplify it into its canonical form. Don’t forget that most test creators put answers in this form, taking this step can help you make it apparent that your answers are equal. When dealing with free-response exams, professors provide such instructions as simplifying radicals, and this means that you need to take this step until your answers satisfy a canonical form. The same rule is applied to solving equations, although some of them are much easier to handle in their non-canonical form.

A Few Important Questions to Answer

What do you think about radicals? As a good math student, you need to understand the role they play in this field and have a clear idea of radical expressions and the process of simplifying radicals. There are certain questions that should be answered to achieve this academic goal.

What are radical expressions are all about? Keep in mind that there are 3 parts of them that you need to understand, and the first one is a radical symbol (root of) used to differentiate radical expressions from others. Pay attention to the number under this symbol and learn that it’s called a radicand. It’s all about the expression or a number that you’re finding the root of. Take into account a smaller number that comes with a radical symbol, and it’s called the index. If you can’t see any index, feel free to support that this number is 2.

What should you know about simplifying radicals? It’s possible to call radical expressions simplified only when there is no perfect root factor left in their radical. Ensure that there are no fractions in radicals, while fractions can’t have radicals in denominators. If you need to complete this math task, pay attention to a few useful properties: quotient and product properties of radicals.

What is a product property? It’s quite useful when you don’t have perfect roots as radicands, but you have perfect roots as factors. This is when you need to take square roots for all factors.

What about a quotient property? You should use it when dealing with radicands that come as fractions, and their denominators and numerators can be separated into radicals that you can simplify. As you can see, this process requires simplifying radicals.

Remember that the simplified answers you get can remain as fractions, but their denominators can’t be radicals. If they contain radicals, both denominators and numerators can be multiplied by the radicals you see in denominators. Don’t forget that radicands can be numbers, variables, and their combinations. Be sure to apply a radical symbol to all of its parts.

The Main Steps Involved in This Process

You may need to check the rules applied to manipulating exponents and radicals because most of them are needed to complete the process of simplifying radicals. Besides, you should review the rules for simplifying and manipulating rational and polynomial expressions because you will need them. There are different methods that can be used to complete this academic task.

For example, concentrate on perfect powers when simplifying those radical expressions that are called perfect squares. The latter ones are the products of those numbers that can multiply by themselves. If you need to simplify perfect squares under radicals, it’s necessary to remove their radical signs and write the number you see in a square root of their perfect squares. You also need to get more information about simplifying radicals as perfect cubes. The latter ones are the products of those numbers that can be multiplied by themselves twice. When you need to simplify radical expressions with perfect cubes under cube root signs, remove their radical signs and write the number you see in their cube roots.

Find out more about converting rational exponents to radical because this knowledge will come in handy when simplifying radicals. Look for fractional exponents and convert them into radical equivalents. If you gave fractions for their index, you should get rid of them and make sure that you convert all negative exponents to equivalent fractions. The last step that should be taken is combining like terms before you simplify rational expressions that will result.

Another popular method used by many math students is removing fractions from radicals. Keep in mind that canonical forms require expressing the roots of fractions in terms of the roots of whole numbers. You need to check terms under all radicals to define whether any of them include fractions. It’s necessary to replace any fraction you find as a ratio of 2 radicals and simplify the perfect squares that result. Be sure to make other helpful simplifications, including combining similar terms and reducing compound fractions to succeed.

When simplifying radicals, it’s also possible to combine their products. For example, if you have only one radical expression that is multiplied by another, you need to combine them as 1 radical. Try to extract square factors from radicals to achieve the same goal. This process starts with factorizing imperfect radical expressions into their price factors, which are the numbers that can multiply to create a number. If you need to break down imperfect radical expressions, write down all of its factors to come up with the one that is called a perfect square. Your next step when simplifying radicals is removing those multiples that are considered perfect squares out of radical signs. You also need to find perfect squares in variables before pulling them out of radical signs. It’s required to combine all like terms and simplify any rational expression that results to get the right answer.

In addition, you can try to rationalize denominators when simplifying radicals. That’s because canonical forms require denominators to be whole numbers if possible. If they consist of single terms under radicals, you should multiply numerators and denominators by a given radical. If denominators include a difference or sum of square roots, multiply them and numerators by their conjugate. Feel free to use this helpful trick to decrease or eliminate a number of radical signs. The good news is that it even works for the denominators that contain higher roots. When given denominators are rationalized, you may end up with numerators that are in the mess. Go ahead and keep expanding these products and check whether anything cancels when simplifying radicals. However, if your denominators are negative integers, you need to multiply them and numerators by -1.

Easy and Effective Simplifying Tips

If you have certain problems with simplifying radicals, remember that there are many sites that can help you. The best part is that most of them can complete this task automatically so that you only need to type in equations under radical signs to get the right answer fast and easily. When dealing with simple problems, some of the above-mentioned steps won’t apply, but if you need to solve complex math problems, you may have to take them more than once.

It’s advisable to make easy simplifications continuous as you keep doing your homework, and be sure to check all final answers against the important criteria of canonical forms. If they are not canonical, you still need to take a few more steps to succeed. If some of the above-mentioned ideas or tips seem contradictory and ambiguous to you, you should apply all unambiguous and consistent steps to get correct answers. If you still have certain difficulties, don’t hesitate to contact credible and trained freelancers who will provide you with the guidance you need to get higher grades.
