Answer 1

Resposta:

$a)$ $622$  ;  $b)$ $\frac{7}{8}$

Explicação passo-a-passo:

a) $\frac{(5.5)^{2}+(-3)^{3}:(-3)^{2}}{10^{0}}$

   $\frac{25^{2}+(-3).(-3).(-3):(-3).(-3)}{1}$

   $25.25-27:9=625-3=622$

------------------------------------------------------------------------

b) $\frac{-2^{3}+(6:6)^{2}-0^{12}}{-2^{3} }$

   $\frac{-(2.2.2)+(1)^{2}-0}{-(2.2.2)}$

   $\frac{-8+1}{-8}=\frac{-7}{-8}=\frac{7}{8}$
