[tex]2^{3} =2\cdot2\cdot2=\boxed{8}[/tex]
[tex](\frac{3}{5})^{2} = \ \frac{3}{5} \cdot \frac{3}{5}=\boxed{\frac{9}{25} }[/tex]
[tex](-1)^{5} =(-1)\cdot(-1)\cdot(-1)\cdot(-1)\cdot(-1)=\boxed{-1}[/tex]
[tex](-7)^{0} =\boxed{1}[/tex]
b)
[tex](1\frac{2}{5} )^{2} = \frac{7}{5} \cdot\frac{7}{5}=\boxed{\frac{49}{25} }[/tex]
[tex](-2\frac{1}{2} )^{3} =(-\frac{5}{2} )\cdot(-\frac{5}{2} ) \cdot(-\frac{5}{2} )=\boxed{-\frac{125}{8} }[/tex]
