Question

(1/4)2. (1/9)3. (2/5)3. (4/7)3

Answer 1

$(\frac{1}{4} )^{2} = \frac{1}{4}$·$\frac{1}{4} = \frac{1}{16}$

$(\frac{1}{9}) ^{3} = \frac{1}{9}$·$\frac{1}{9}$·$\frac{1}{9}$ = $\frac{1}{729}$

$(\frac{2}{5}) ^{3} = \frac{2}{5} *\frac{2}{5} * \frac{2}{5} = \frac{8}{125}$

$(\frac{4}{7}) ^{3} = \frac{4}{7} *\frac{4}{7} *\frac{4}{7} = \frac{64}{343}$
