# Chapter 1 - Section 1.2 - Exponents and Radicals - 1.2 Exercises: 23

a) $6$$\sqrt[3] 2 b) \frac{\sqrt 2}{3} c) \frac{3\sqrt 3}{2} #### Work Step by Step a) 3$$\sqrt[3] {16}$= $3$$\times(4^{2})^{1/3} = 3$$\times$($2^{4}$)$^{1/3}$ = $6$$\sqrt[3] 2$ b) $\frac{\sqrt {18}}{\sqrt {81}}$= $\frac{\sqrt 9 \times \sqrt 2}{\sqrt 9 \times \sqrt 9}$ = $\frac{\sqrt 2}{3}$ c) $\sqrt {\frac{27}{4}}$ = $\sqrt {\frac{9\times3}{4}}$ = $\frac{\sqrt 9 \times \sqrt3}{\sqrt4}$ = $\frac{3\sqrt 3}{2}$
