$( \frac{3}{2} ) { - }^{2} + \frac{7}{4}$
​

Answer 1

Resposta:

Olá bom dia!

Lembrando que:

$(\frac{a}{b} )^{-n} = (\frac{b}{a} )^n$

Logo:

$(\frac{3}{2})^{-2} + \frac{7}{4} \\\\= (\frac{2}{3} )^2 + \frac{7}{4} \\\\\\= \frac{4}{9} + \frac{7}{4} \\\\= \frac{4.4+9.7}{36} \\\\= \frac{16+63}{36} \\\\= \frac{79}{36}$
