Step-by-step explanation:

Given

- ([tex]\frac{2}{5}[/tex] )²

The negative is outside the bracket and is not squared, that is

= - [tex]\frac{2}{5}[/tex] × [tex]\frac{2}{5}[/tex]

= - [tex]\frac{2(2)}{5(5)}[/tex] = - [tex]\frac{4}{25}[/tex]

Given

[tex]\frac{5^3}{3}[/tex] = [tex]\frac{5(5)(5)}{3}[/tex] = [tex]\frac{125}{3}[/tex]
