Question

calcule as expressoe utilizando alguma propriedade de potencia 
  [ (- 3)$- 3^{2}$

[$[ (\frac{1}{2}) ^{3} ] ^{-2}$


me ajudeeeeee

Answer 1

$\boxed{[(-3)^2]^{-1}~\to~(-3)^{-2}~\to~ \frac{1}{(-3)^2} ~\to~ \frac{1}{9} }}$


$\boxed{[( \frac{1}{2} )^3]^{-2}~\to~( \frac{1}{2} )^{-6}~\to~ \frac{1}{( \frac{1}{2} )^6} ~\to~ \frac{1}{ \frac{1}{64} } \to~64}}$
