${(0.3 {x}^{2} {y}^{3}) }^{3} \times {( - 3 \frac{1}{3 }x {y}^{4} ) }^{2} = \\ = {(0.3 {x}^{2} {y}^{3} ) }^{3} \times {( - \frac{10}{3}x {y}^{4}) }^{2} = \\ = 0.0027 {x}^{6} {y}^{9} \times \frac{100}{9} {x}^{2} {y}^{8} = \\ = \frac{27}{1000} {x}^{6} {y}^{9} \times \frac{100}{9} {x}^{2} {y}^{8} = \\ = \frac{3}{10} {x}^{8} {y}^{17} = 0.3 {x}^{8} {y}^{17}$
