derivative of

f (x) = \frac{12 - 8 x}{5 x ^{\frac{2}{5}}}

\frac{- 24 x - 24}{25 x ^{\frac{7}{5}}}

Solution steps

\frac{d}{d x} (\frac{12 - 8 x}{5 x ^{\frac{2}{5}}})

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= \frac{1}{5} \frac{d}{d x} (\frac{12 - 8 x}{x ^{\frac{2}{5}}})

Apply the Quotient Rule:

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

= \frac{1}{5} \cdot \frac{\frac{d}{d x} ( 12 - 8 x ) x ^{\frac{2}{5}} - \frac{d}{d x} ( x ^{\frac{2}{5}} ) ( 12 - 8 x )}{( x ^{\frac{2}{5}} ) ^{2}}

\frac{d}{d x} (12 - 8 x) = - 8

\frac{d}{d x} (x^{\frac{2}{5}}) = \frac{2}{5 x ^{\frac{3}{5}}}

= \frac{1}{5} \cdot \frac{( - 8 ) x ^{\frac{2}{5}} - \frac{2}{5 x ^{\frac{3}{5}}} ( 12 - 8 x )}{( x ^{\frac{2}{5}} ) ^{2}}

Simplify

\frac{1}{5} \cdot \frac{( - 8 ) x ^{\frac{2}{5}} - \frac{2}{5 x ^{\frac{3}{5}}} ( 12 - 8 x )}{( x ^{\frac{2}{5}} ) ^{2}} : \frac{- 24 x - 24}{25 x ^{\frac{7}{5}}}

= \frac{- 24 x - 24}{25 x ^{\frac{7}{5}}}

\int \frac{x ^{2} - 81}{x} d x

\int \frac{( x ^{2} - 1 )}{( x ^{2} + 1 ) ( x - 2 )} d x

\frac{\partial}{\partial x} (\frac{5 x - 3 y}{5 x + 3 y})

\int x^{2} cos (x^{3}) d x

x \to 1 lim (- x^{2} + 9 x - 7)
