Answer 1

Olá

A)

$\LARGE{}x = {4}^{3} \times 3 \div 2 \\ \LARGE{}x = {2}^{6} \times 3 \div 2 \\ \LARGE{}x = {2}^{5} \times 3 \\ \LARGE{} x = 32 \times 3 \\ \LARGE{}\LARGE\boxed{x = 96}$

B)

$\LARGE{}x = {5}^{4} \times 8 \div 2 \\ \LARGE{}x = {5}^{4} \times 4 \\ \LARGE{}x = 4 \times {5}^{4} \\ \LARGE{}x = 4 \times 625 \\ \LARGE{}\LARGE\boxed{x = 2500}$

C)

$\LARGE{}x = {6}^{3} \times 4 \div 3 \\ \\ \LARGE{}x = \frac{ {6}^{3} \times 4 }{3} \\ \\ \LARGE{}x = \frac{4 \times {6}^{3} }{3} \\ \\ \LARGE{}x = \frac{4 \times 216}{3} \\ \\ \LARGE{}x = \frac{4 \times \cancel{216}}{\cancel{3}} \\ \\ \LARGE{}x = 4 \times 72 \\ \\ \LARGE\boxed{x = 288}$
