Answer 2

$(\frac{4}{5})^2=\frac{4^2}{5^2}=\frac{16}{25}\\\\(\frac{2}{3})^2=\frac{4}{9}\\\\(1\frac{1}{2})^2=(\frac{3}{2})^2=\frac{9}{4}\\\\(-2\frac{1}{4})^2=(-\frac{9}{4})^2=+\frac{81}{16}\\\\(2,1)^2=4,41\\\\(-6)^3=-6^3=-216\\\\9^3=729\\\\(1\frac{3}{4})^3=(\frac{7}{4})^3=\frac{343}{64}\\\\(-1,2)^3=-(1,2)^3=-1,728$
