Answer 1

$\large\boxed{\begin{array}{l}\tt a)~\sf\bigg(-\dfrac{3}{2}\bigg)^2=\dfrac{9}{4}\\\tt b)~\sf\bigg(+\dfrac{5}{4}\bigg)^2=\dfrac{25}{16}\\\tt c)~\sf\bigg(-\dfrac{1}{2}\bigg)^5=-\dfrac{1}{32}\\\tt d)~\sf\bigg(-\dfrac{15}{8}\bigg)^0=1\end{array}}$

$\large\boxed{\begin{array}{l}\tt e)~\sf(+1,7)^2=2,89\\\tt f)~\sf(-10)^5=-100~000\\\tt g)~\sf(-1)^{200}=1\\\tt h)~\sf(-0,4)^3=-0,064\end{array}}$
