GOAL: USE PROPERTIES OF RADICALS AND RATIONAL EXPONENTS

Section 7-2: Properties of Rational Exponents

Example 1: Use Properties of Radicals

Simplifying Radicals

A radical with index n is in simplest form if :

there are no perfect nth powers in the radicand.

there are no radicals in the denominators.
