Question

Socorooooooooooooooooooooooooooooo

Answer 1

Explicação passo-a-passo:

A)

$\frac{ { - 8}^{2} }{ {( \frac{3}{2} )}^{2} - {( \frac{1}{2}) }^{2} }$

$\frac{ - 64}{ {( \frac{3}{2} ) }^{2} - {( \frac{1}{2} )}^{2} }$

$\frac{ - 64}{ \frac{9}{4} - \frac{1}{4} }$

$\frac{ - 64}{2}$

Reduza a fração por 2

$- 32$

B)

$10 \times { ( - \frac{2}{3} )}^{2} + 8 \times { ( - \frac{1}{2} )}^{3}$

$10 \times {( \frac{2}{3} )}^{2} + 8 \times {( - \frac{1}{2} )}^{3}$

$10 \times {( \frac{2}{3} )}^{2} + 8 \times ( - { (\frac{1}{2} )}^{3} )$

$10 \times \frac{4}{9} + 8 \times ( - { (\frac{1}{2} )}^{3} )$

$10 \times \frac{4}{9} - 8 \times { (\frac{1}{2}) }^{3}$

$10 \times \frac{4}{9} - 8 \times \frac{1}{8}$

$10 \times \frac{4}{9} - 1$

$\frac{40}{9} - 1$

$\frac{31}{9}$
