Answer 2

Resposta:

Espero ter ajudado!!!

Explicação passo-a-passo:

a) $(\frac{3}{2} )^{-2}$ => $(\frac{2}{3}) ^{2}$ => $(\frac{2}{3}) }. (\frac{2}{3})$   = $+\frac{4}{9}$            

b) $(\frac{1}{2})^{-3}$ => $(+2)^{3}$ => (+2).(+2).(+2)= +8

c) $(\frac{2}{3} )^{-2}$ => $(\frac{3}{2})^{2}$ => $(\frac{3}{2}).(\frac{3}{2})$ = $(+\frac{9}{4})$    

d) $(\frac{1}{4})^{-2}$ => $(+4)^{2}$ => $(+4).(+4)$ = +16

e) $(\frac{5}{2})^{-3}$ => $(\frac{2}{5})^{3}$ => $(\frac{2}{5}).(\frac{2}{5}).(\frac{2}{5})$ => $(+\frac{8}{125})$
