Alguem pode me ajudar

Answer 1

Resposta:

$A)2^{-3} = \frac{1}{2^{3} } =\frac{1}{8}=0,125$

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

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

$D)(\frac{3}{4} )^{-5} =(\frac{4}{3} )^{5} =\frac{1024}{243}$

$E)(-\frac{2}{5} )^{-4} =(-\frac{5}{2} )^{4} =\frac{625}{16}$
