chapter 5 Exponents and Roots

Expressions involving roots and exponents occur frequently in algebra and cal-

culus. By mastering the properties in this chapter, you will find working with

such expressions much easier. Here, we learn exponent and root properties,

how to use them to rewrite some expressions, and how to simplify others. We

will use these properties later to solve equations.

CHAPTER OBJECTIVES

In this chapter, you will

• Use exponent properties to rewrite expressions


• Use exponent properties to perform arithmetic


• Use exponent properties to simplify fractions


• Write a fraction as a product


• Use root properties to rewrite expressions
