Olá!!  :)

$\sf ITEM \ (A): \\\\ 8^{-2} \ \ \Rightarrow \ \ (\frac{1}{8})^{2} \ \ \Rightarrow \ \ \boxed{ \ \frac{1}{64} \ } \\\\ \\\\ ITEM \ (B): \\\\ 5^{-1} \ \ \Rightarrow \ \ (\frac{1}{5})^{1} \ \ \Rightarrow \ \ \boxed{ \ \frac{1}{5} \ } \\\\ \\\\ ITEM \ (C): \\\\ (-2)^{-4} \ \ \Rightarrow \ \ -\frac{1}{2^{4}} \ \ \Rightarrow \ \ \boxed{ \ -\frac{1}{16} \ } \\\\ \\\\ ITEM \ (D): \\\\ (\frac{1}{2})^{-3} \ \ \Rightarrow \ \ (\frac{2}{1})^{3} \ \ \Rightarrow \ \ \boxed{ \ 8 \ }$

$\sf ITEM \ (E): \\\\ (-3)^{-3} \ \ \Rightarrow \ \ -\frac{1}{ \ 3^{3} } \ \ \Rightarrow \ \ \boxed{ \ -\frac{1}{27} \ } \\\\ \\\\ ITEM \ (F): \\\\ (\frac{1}{2})^{-5} \ \ \Rightarrow \ \ (\frac{2}{1})^{5} \ \ \Rightarrow \ \ \boxed{ \ 32 \ }$

Espero ter ajudado, bons estudos!!  :)
