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 n th powers in the radicand. there are no radicals in the denominators.
