Answer 2

Resposta:

Olá,

Boa noite!

Respostas:

$a)625$

$b) \frac{8}{27}$

$c) - 64$

$d) \frac{1}{32}$

Explicação passo-a-passo:

Resolução:

$a) {5}^{4} =$

$5 \times 5 \times 5 \times 5 =$

$25 \times 5 \times 5 =$

$125 \times 5 =$

$625$

$b) (\frac{2}{3} )^{3} =$

$\frac{2 ^{3} }{3^{3} } =$

$\frac{2 \times 2 \times 2}{ {3}^{3} } =$

$\frac{4 \times 2}{ {3}^{3} } =$

$\frac{8}{ {3}^{3} } =$

$\frac{8}{ 3 \times 3 \times 3 } =$

$\frac{8}{9 \times 3 } =$

$\frac{8}{27 }$

$c)( - 4)^{3} =$

$- 4 ^{3} =$

$- (4 \times 4 \times 4) =$

$- (16 \times 4) =$

$- 64$

$d)( \frac{1}{2} )^{5} =$

$\frac{1^{5} }{2 ^{5} } =$

$\frac{1}{ {2}^{5} } =$

$\frac{1}{2 \times 2 \times 2 \times 2 \times 2} =$

$\frac{1}{4 \times 2 \times 2 \times 2} =$

$\frac{1}{8 \times 2 \times 2} =$

$\frac{1}{16 \times 2} =$

$\frac{1}{32}$
