Answer 1

(2/9)² = 4/81
(2/3)³ = 8/27
(1/4)³ = 1/64
(4/3)² = 16/9 = 1 7/9
(1/5)³ = 1/125
(3/7)²  = 9/49

Answer 2

                                                       837
1. ( $\frac{2}{9}$ ) ^ 2 = $\frac{2 ^ 2}{9 ^ 2} = [tex] \frac{4}{81}$} [/tex]

2. ( $\frac{2}{3}$ ) ^ 3= $\frac{2 ^ 3}{3 ^ 3}$ = $\frac{8}{27}$

3. ( $\frac{1}{4}$ ) ^ 3 = $\frac{1 ^ 3}{4 ^ 3}$ = $\frac{1}{64}$
