${ (\frac{ - 1}{5}) }^{3} \times {( - 1)}^{85} \times { (\frac{2}{5} )}^{2}$
$= \frac{( - 1) \times ( - 1) \times ( {2})^{2} }{ {(5)}^{3} \times {(5)}^{2} }$
$= \frac{4}{ {5}^{5} }$
=4/3125.

Answer 2

Hi ,

( -1/5 )³ × ( -1 )^85 × ( 2/5 )²

= ( - 1/ 125 ) × ( - 1 ) × 4/25

= 4 / ( 125 × 25 )

= 4/3125

I hope this helps you.
