Step-by-step explanation:
[tex] \frac{2 {}^{4} }{3 \sqrt{xy} } [/tex]
[tex] \frac{2 { }^{4} }{ \sqrt{9xy} } [/tex]
[tex] \frac{1}{2 {}^{ - 4} \sqrt{9xy} } [/tex]
[tex] \frac{1}{ \frac{ \sqrt{9xy} }{16} } [/tex]
[tex] \frac{1}{ \frac{ \sqrt{9xy} }{ \sqrt{256} } } [/tex]
[tex] \frac{1}{ \sqrt{ \frac{9xy}{256} } } [/tex]
[tex]( \sqrt{ \frac{9xy}{256} } ) {}^{ - 1} [/tex]
