Answer 2

$- (\frac{2}{3} x^{2} y^{2})^{4} * (-2 \frac{1}{4} xy^{3})^{3} = - (\frac{2}{3} x^{2} y^{2})^{4} * (-(2*\frac{1}{4} xy^{3} )^{3}) = \frac{16}{81} x^{8} y^{8} * (\frac{1}{2} xy^{3})^{3} = \frac{16}{81} x^{8} y^{8} * \frac{1}{8} x^{3} y^{9} = \frac{2}{81} x^{8} y^{8} x^{3} x^{9} = \frac{2}{81}x^{11}  y^{17}$
