# Chapter 1 - Section 1.2 - Exponents and Radicals - 1.2 Exercises: 31

a) $\frac{1}{x^2}$ b) $\frac{1}{w}$ c) $x^6$

#### Work Step by Step

a) $x^{-5}$$x^3 = x^{-5+3} = x^-2 = \frac{1}{x^2} b) w^{-2}$$w^{-4}$$w^{5}$ = $w^{-2-4+5}$ = $w^{-1}$ = $\frac{1}{w}$ c) $\frac{x^{16}}{x^{10}}$ = $x^{16-10}$ = $x^{6}$
