Understanding Rational Exponents

The video tutorial explains how to convert radical expressions into rational exponents by identifying the index of the radical as the denominator and the exponent as the numerator. It provides examples such as square roots and cube roots, demonstrating how to rewrite them using rational exponents. The tutorial also covers more complex examples, including the fifth root and expressions with multiple variables, and shows alternative methods for simplification. The video concludes with a promise of more examples in future videos.

What is the denominator of the rational exponent when converting a radical expression?

• The index of the radical

• The exponent of the base

• The base of the expression

• The coefficient of the radical
