\frac{d}{d x} ((\frac{4 x ^{2}}{8 - x})^{3})

\frac{192 x ^{4} ( 16 x - x ^{2} )}{( 8 - x ) ^{4}}

Solution steps

\frac{d}{d x} ((\frac{4 x ^{2}}{8 - x})^{3})

Apply the chain rule:

3 (\frac{4 x ^{2}}{8 - x})^{2} \frac{d}{d x} (\frac{4 x ^{2}}{8 - x})

= 3 (\frac{4 x ^{2}}{8 - x})^{2} \frac{d}{d x} (\frac{4 x ^{2}}{8 - x})

\frac{d}{d x} (\frac{4 x ^{2}}{8 - x}) = \frac{4 ( 16 x - x ^{2} )}{( 8 - x ) ^{2}}

= 3 (\frac{4 x ^{2}}{8 - x})^{2} \frac{4 ( 16 x - x ^{2} )}{( 8 - x ) ^{2}}

Simplify

3 (\frac{4 x ^{2}}{8 - x})^{2} \frac{4 ( 16 x - x ^{2} )}{( 8 - x ) ^{2}} : \frac{192 x ^{4} ( 16 x - x ^{2} )}{( 8 - x ) ^{4}}

= \frac{192 x ^{4} ( 16 x - x ^{2} )}{( 8 - x ) ^{4}}
