b)64/27

c)1/49

f)81/16

Explicação passo-a-passo:

Answer 2

Resposta:

$b)2^{-5} =\frac{1}{2^{5} } =\frac{1}{32} =0,03125$

$c)7^{-2} =\frac{1}{7^{2} } =\frac{1}{49} =0,0204082$

$e)(\frac{3}{4} )^{-3} =(\frac{4}{3} )^{3} =\frac{64}{27}$

$f)(-\frac{2}{3} )^{-4} =(-\frac{3}{2} )^{4} =\frac{81}{16}$
