Question

alguem me ajuda nessa pelo amor de Deus

Answer 1

Explicação passo-a-passo:

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

$= \frac{ \frac{1}{8} - ( - 8) }{ \frac{1}{8} + ( - 8) }$

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

$= \frac{ \frac{(1 + 64)}{8} }{ \frac{(1 - 64)}{8} }$

$= - \frac{ \frac{65}{8} }{ \frac{63}{8} }$

$= - ( \frac{65}{8} \times \frac{8}{63} )$

$= - \frac{65}{63}$
