derivative of

2 x^{- \frac{3}{4}}

- \frac{3}{2 x ^{\frac{7}{4}}}

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule:

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

= 2 (- \frac{3}{4} x^{- \frac{3}{4} - 1})

Simplify

2 (- \frac{3}{4} x^{- \frac{3}{4} - 1}) : - \frac{3}{2 x ^{\frac{7}{4}}}

= - \frac{3}{2 x ^{\frac{7}{4}}}
