a) $(\frac{2}{3})^{3}$ = $\frac{2^{3}}{3^{3}}$ = $\frac{8}{27}$; b) $(-2\frac{3}{4})^{2}$ = $(\frac{-11}{4})^{2}$ = $\frac{(-11)^{2}}{4^{2}}$ = $\frac{121}{16}$;
c) (0,6)$^{4}$ = $(\frac{3}{5})^{4}$ = $\frac{3^{4}}{5^{4}}$ = $\frac{81}{625}$; d) $(\frac{-1}{2})^{4}$ = $\frac{(-1)^{4}}{2^{4}}$ = $\frac{1}{16}$;
e) $(\frac{-1}{2})^{5}$ = $\frac{(-1)^{5}}{2^{5}}$ = $\frac{-1}{32}$.
