Answer 1

$2^{-2}$ = $( \frac{1}{2} )^{2}$ = $\frac{1}{4}$ 
$5^{-3}$ = $( \frac{1}{5} )^{3}$ = $\frac{1}{125}$
$( \frac{1}{2} )^{-2}$ = $2^{2}$ = 4
$6^{-4}$ = $( \frac{1}{6} )^{4}$ = $\frac{1}{1296}$ 
$( \frac{2}{3} )^{-3}$ = $( \frac{3}{2} )^{3}$ = $\frac{27}{8}$
$4^{-6}$ = $( \frac{1}{4} )^{6}$ = $( \frac{1}{4096} )$
$( \frac{5}{3} )^{-2}$ = $( \frac{3}{5} )^{2}$ = $( \frac{9}{25} )$
$3^{-5}$ = $( \frac{1}{3} )^{5}$ = $( \frac{1}{243} )$
$( \frac{1}{7} )^{-1}$ = 7
