\frac{d}{d x} (\frac{21}{64 x ^{\frac{11}{4}}})

- \frac{231}{256 x ^{\frac{15}{4}}}

Solution steps

\frac{d}{d x} (\frac{21}{64 x ^{\frac{11}{4}}})

Take the constant out:

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

= \frac{21}{64} \frac{d}{d x} (\frac{1}{x ^{\frac{11}{4}}})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= \frac{21}{64} \frac{d}{d x} (x^{- \frac{11}{4}})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= \frac{21}{64} (- \frac{11}{4} x^{- \frac{11}{4} - 1})

Simplify

\frac{21}{64} (- \frac{11}{4} x^{- \frac{11}{4} - 1}) : - \frac{231}{256 x ^{\frac{15}{4}}}

= - \frac{231}{256 x ^{\frac{15}{4}}}
