Answer 1

Olá, tudo bem ?

Veja a resolução abaixo ⇩

$\boxed{\begin{array}{lr}( \frac{1}{5} {)}^{ - 2} \times ( \frac{2}{3} {)}^{3} + {3}^{ - 2} \times {3}^{5} \\ \\ \: \: \: {5}^{2} \times ( \frac{2}{3} {)}^{3} + {3}^{ - 2} \times {3}^{5} \\ \\ \: \: \: \: {5}^{2} \times \frac{8}{27} + {3}^{ - 2} \times {3}^{5} \\ \\ \: \: \: \: \: \: \: \: \: {5}^{2} \times \frac{8}{27} + {3}^{3} \\ \\ \: \: \: \: \: \: \: \: \: 25 \times \frac{8}{27} + {3}^{3} \\ \\ \: \: \: \: \: \: \: \: 25 \times \frac{8}{27} + 27 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \frac{200}{27} + 27 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{\boxed{\red { \frac{929}{27} }}} {\green{ \: ⇒resposta✓}} \end{array}}$
