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

\frac{12 x ^{3} - x ^{6}}{( 3 - x ^{3} ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

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

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

Simplify

\frac{4 x ^{3} ( 3 - x ^{3} ) - ( - 3 x ^{2} ) x ^{4}}{( 3 - x ^{3} ) ^{2}} : \frac{12 x ^{3} - x ^{6}}{( 3 - x ^{3} ) ^{2}}

= \frac{12 x ^{3} - x ^{6}}{( 3 - x ^{3} ) ^{2}}
