# Roots and Powers

## The Relationship Between Roots and Powers

Property â€” Taking the nth Root of an nth Power

 Examples if n is an odd positive integer and x is any real number.  if n is an even positive integer and x ≥ 0.  if n is an even positive integer and x < 0. = -1(-17)= 17

Example 1

Simplify: Solution

Use this relationship to simplify each radical:  Example 2

Simplify: Solution

This has the form where x < 0.

Therefore, use this relationship: = -1 Â· x.
