Defining powers this way makes the laws of powers continue being valid, for fractional exponents. Mainly, as you might know, (ab)c = abc. For positive integers "b" and "c", this is easy to visualize. Now, for example, for (21/2)2, you would expect the result to be 2 according to this law. This is only possible if 21/2 is equal to the square root of 2.

What is the difference between a radical and rational exponents?
In terms of mathematical concepts, there is no difference at all. In practical terms, some rational exponents or rational number will result in rational answers while radical exponent won't. But that is hardly a significant difference.
Can you Define and explain radical expressions?
A rational expression is an expression that contains a radical, i.e., a root.
What is rational exponent notation?
rational numbers are commonly referred to as fractions Any root ... square root, cube root, etc can be expressed as a rational exponent sq rt of x = x1/2 cube root of x = x1/3 if there is an exponent inside the radical you can also have rational exponents with some numerator other than 1 ex 4th root of x3 = x3/4

How do you rewrite expressions with rational exponent as radical exponent?
In this tutorial we are going to combine two ideas that have been discussed in earlier tutorials: exponents and radicals. We will look at how to rewrite, simplify and evaluate these expressions that contain rational exponents. What it boils down to is if you have a denominator in your exponent, it is your index or root number. So, if you need to, review radicals covered in Tutorial 37: Radicals. Also, since we are working with fractional exponents and they follow the exact same rules as integer exponents, you will need to be familiar with adding, subtracting, and multiplying them. If fractions get you down you may want to go to Beginning Algebra Tutorial 3: Fractions. To review exponents, you can go to Tutorial 23: Exponents and Scientific Notation Part I andTutorial 24: Exponents and Scientific Notation Part II. Let's move onto rational exponents and roots.After completing this tutorial, you should be able to:Rewrite a rational exponent in radical notation.Simplify an expression that contains a rational exponent.Use rational exponents to simplify a radical expression.These are practice problems to help bring you to the next level. It will allow you to check and see if you have an understanding of these types of problems. Math works just like anything else, if you want to get good at it, then you need to practice it. Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument. In fact there is no such thing as too much practice.To get the most out of these, you should work the problem out on your own and then check your answer by clicking on the link for the answer/discussion for that problem. At the link you will find the answer as well as any steps that went into finding that answer.

How are rational exponents related to radicals?
You can represent a radical with a rational exponent. For example the nth root of a number m can be written as m1/n . If n was 2 for example, then it is the square root. So square root of 3 or radical 3 is written sqrt(3) or 31/2 .
