Answer 1

Resposta:

$A)(\frac{5}{8} )^{-2} =(\frac{8}{5} )^{2} =\frac{64}{25}$

$B)(\frac{9}{4} )^{-1} = \frac{4}{9}$

$C)(\frac{1}{4} )^{-3} =4^{3} =64$

$D)(-\frac{7}{5} )^{-2} = (-\frac{5}{7} )^{2} =\frac{25}{49}$

$E)(-\frac{1}{6} )^{-2} =(-6)^{2} =36$  

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