Answer 1

$( { \sqrt{x} }^{ \frac{ - 2}{3} } \sqrt{ {y}^{4} } \sqrt{ {xy}^{ \frac{ - 1}{2} } } \sqrt{ {x}^{ - 2} {y}^{3} }$

$= {x}^{ \frac{ - 1}{3} } {y}^{ \frac{1}{2} } {x}^{ \frac{ - 1}{4} } {y}^{ \frac{ - 1}{4} } {x}^{ - 1} {y}^{ \frac{3}{2} }$

$= {x}^{ \frac{ - 1}{3} + \frac{ - 1}{4} + - 1 } {y}^{ \frac{1}{2} + \frac{ - 1}{4} + \frac{3}{2} }$

$= {x}^{ \frac{ - 19}{12} } {y}^{ \frac{7}{4} }$
