Answer 1

$( \frac{ {x}^{2} {y}^{ - 3} }{6 {z}^{2} } ) ^{ - 3} \times ( { \frac{ {x}^{2} {y}^{ - 2} }{9 {z}^{3} } })^{2} = (6 {z}^{2} \div \frac{ {x}^{2} }{ {y}^{3} } ) {}^{3} \times ( \frac{ {x}^{2} }{ {y}^{2} } \div 9 {z}^{3} ) {}^{2} = (6 {z}^{2} \times \frac{ {y}^{3} }{ {x}^{2} } ) {}^{3} \times ( \frac{ {x}^{2} }{ {y}^{2} } \times \frac{1}{9 {z}^{3} } ) {}^{2} =( \frac{6{y}^{3} {z}^{2} }{ {x}^{2} }) {}^{3} \times ( \frac{ {x}^{2} }{9 {y}^{2} {z}^{3} } ) {}^{2} = \frac{216 {y}^{9} {z}^{6} }{ {x}^{6} } \times \frac{ {x}^{4} }{81 {y}^{4} {z}^{6} } = \frac{8 {y}^{5} }{3 {x}^{2} }$
