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]
