$( - \frac{2}{3} {x}^{3} y {)}^{2} \times ( - 1 \frac{1}{2} x {y}^{3} {)}^{3} = ( \frac{2}{3} {x}^{3} y {)}^{2} \times ( - (1 \times \frac{1}{2} x {y}^{3} {)}^{3} ) = \frac{4}{9} {x}^{6} {y}^{2} \times ( - ( \frac{1}{2} x {y}^{3} {)}^{3} ) = - \frac{4}{9} {x}^{6} {y}^{2} \times \frac{1}{8} {x}^{3} {y}^{9} = - \frac{1}{9} {x}^{6} {y}^{2} \times \frac{1}{2} {x}^{3} {y}^{9} = - \frac{1}{18} {x}^{9} {y}^{11}$
