→ Cálculo :

⇔ Resposta : 625/16

$\large\boxed{\begin{array}{lr} {\left ( -\frac{2}{5} \right )^{-4}= \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ } \\ \\ {\left ( -\frac{5}{2} \right )^{4} }=\\\\{\left ( \frac{5}{2} \right )^{4} = }\\\\{ \large \frac{5^{4} }{2^{4} } =} \\\\\boxed{\red{\large\frac{625}{16}}} \\ \end{array}}$
