In this lesson, you will learn what a rational exponent is and how to simplify expressions with rational exponents. A rational exponent is just an exponent that can be written as a fraction. First, we describe how rational exponents can be written in terms of a radical expression. Next, we solve many problems where we must simplify the expression and write the answer either in rational exponent form (fractional exponents) or as a radical expression.
