\frac{d}{d x} (\frac{ln ( x )}{x ^{\frac{5}{4}}})

\frac{4 - 5 ln ( x )}{4 x ^{\frac{9}{4}}}

Solution steps

\frac{d}{d x} (\frac{ln ( x )}{x ^{\frac{5}{4}}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( ln ( x ) ) x ^{\frac{5}{4}} - \frac{d}{d x} ( x ^{\frac{5}{4}} ) ln ( x )}{( x ^{\frac{5}{4}} ) ^{2}}

\frac{d}{d x} (ln (x)) = \frac{1}{x}

\frac{d}{d x} (x^{\frac{5}{4}}) = \frac{5 x ^{\frac{1}{4}}}{4}

= \frac{\frac{1}{x} x ^{\frac{5}{4}} - \frac{5 x ^{\frac{1}{4}}}{4} ln ( x )}{( x ^{\frac{5}{4}} ) ^{2}}

Simplify

\frac{\frac{1}{x} x ^{\frac{5}{4}} - \frac{5 x ^{\frac{1}{4}}}{4} ln ( x )}{( x ^{\frac{5}{4}} ) ^{2}} : \frac{4 - 5 ln ( x )}{4 x ^{\frac{9}{4}}}

= \frac{4 - 5 ln ( x )}{4 x ^{\frac{9}{4}}}
