Question

a)(-4/3)²-(-3/4)⁰ b)(5/2)³+(-5/4)² me ajudemmmmmmm

Answer 1

$( - \frac{4}{3} {)}^{2} - ( - \frac{3}{4} {)}^{0} \\ \frac{16}{9} - 1 \\ \frac{16 - 9}{9} \\ \frac{7}{9} \\ \\ ( \frac{5}{2} {)}^{3} + ( - \frac{5}{4} {)}^{2} \\ \frac{125}{8} + \frac{25}{16} \\ \frac{275}{16}$

Answer 2

Resposta:

a)$\frac{7}{9}$

b)$\frac{275}{16}$

Explicação passo-a-passo:  a)

$\\ (\frac{-4}{3}) ^{2} =\frac{16}{9} \\-(\frac{-3}{4}) ^{0} =-(1) =-1\\\frac{16}{9} - \frac{9}{9} = \frac{7}{9}$

                                     

b)$(\frac{5}{2})^{3}+(\frac{-5}{4})^{2}=\\\\\frac{125}{8}+\frac{25}{16} \\\\\frac{250}{16} +\frac{25}{16} =\frac{275}{16}$
