What is a rational exponent? How are rational exponents related to radicals? Give an example of how an expression with a rational exponent can be rewritten as a radical expression.

Rational exponent: When a number is in the form where both m and n are integers then the exponent is called a rational exponent.

The simplest case of such exponents is where n is an integer other than zero.

When we say , it means .

In other words, when we write , we are asking for the number 'a' that might have been raised to the power n to get b. In this situation, we can ...
