Simplifying a Radical Expression Using the Product Property

To simplify a radical expression using the Product Property of nnth Roots, use the following three-step procedure:

Step 1. Find the largest factor in the radicand that is a perfect power of the index. Rewrite the radicand as a product of two factors, using that perfect power factor. Step 2. Use the Product Property to rewrite the single radical as the product of two separate radicals. Step 3. Simplify the root of the perfect power.

Always write the resulting integer factor in front of the remaining radical. Be careful to write your integer so that it is not confused with the index. The expression 727\sqrt{2} is very different from 27\sqrt[7]{2}.
