Answer 1

Temos os Cálculos:

A)

$\large\boxed{\begin{array}{l} \rm 4^{2}\cdot4^{5} \\ \\ \rm 4^{2+5} \\ \\ \rm 4^{7}\\ \\ \rm 16384 \to Resposta \end{array}}$

B)

$\large\boxed{\begin{array}{l} \rm (-3)^{8}\cdot(-3)^{2} \\ \\ \rm (-3)^{8+2} \\ \\ \rm (-3)^{10}\\ \\ \rm 59049 \to Resposta \end{array}}$

C)

$\large\boxed{\begin{array}{l} \rm \big(-5^{3}\big)^{2} \\ \\ \rm (-5)^{3\times2} \\ \\ \rm (-5)^{6} \\ \\ \rm 15625 \to Resposta \end{array}}$
