=64/15625

Answer 2

$( \frac{ - 2}{5})^{7} \div ( \frac{ -2}{5} )^{2} \times ( \frac{ - 5}{2} )^{ - 2}$

$( \frac{ - 2}{5})^{7 - 3} \times ( \frac{ - 5}{2} )^{ - 2}$

$( \frac{ - 2}{5} )^{4} \times ( \frac{ - 5}{2} )^{ - 2}$

$(\frac{ - 2}{5} )^{4} \times ( \frac{ - 2}{5})^{2}$

$( \frac{ - 2}{5} )^{ 4+ 2}$

$( \frac{ - 2}{5} )^{6}$

$= (\frac{2}{5} )^{6}$
