d)-(-2) ³
e) (2|3) ²

Answer 1

A) 9
B)- 9
D) -16
E)3/2 elevado -2º

Answer 2

$a)(-3)^2=-3\cdot-3=\ \textgreater \ \boxed{9}\\\\b)-3^2=-3\cdot-3=\ \textgreater \ \boxed{9}\\\\c)-2^3=-2\cdot-2\cdot-2=\ \textgreater \ \boxed{-8}\\\\d)-(-2)^3=-(-2\cdot-2\cdot-2)\\-(-8)=\ \textgreater \ \boxed{8} \\\\e)( \frac{2}{3})^2= \frac{2^2}{3^2}=\ \textgreater \ \boxed{\frac{4}{9}}$
