​

Answer 1

$a)\\\\3^{-3}~=~(3)^{-3}~=~\left(\frac{1}{3}\right)^3~=~\frac{1^3}{3^3}~=~\boxed{\frac{1}{9}}\\\\\\b)\\\\(-2)^{-5}~=~\left(~\frac{1}{(-2)}~\right)^5~=~\frac{1^5}{(-2)^5}~=~\frac{1}{-32}~=~\boxed{-\frac{1}{32}}\\\\\\c)\\\\6^{-2}~=~\left(\frac{1}{6}\right)^2~=~\frac{1^2}{6^2}~=~\boxed{\frac{1}{36}}\\\\\\d)\\\\0,3^{-1}~=~\left(\frac{3}{10}\right)^{-1}~=~\boxed{\frac{10}{3}~~ou~~3,333...}$
