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

\frac{3}{x ^{\frac{1}{4}}}

Solution steps

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

Take the constant out:

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

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

Apply the Power Rule:

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

= 4 \cdot \frac{3}{4} x^{\frac{3}{4} - 1}

Simplify

4 \cdot \frac{3}{4} x^{\frac{3}{4} - 1} : \frac{3}{x ^{\frac{1}{4}}}

= \frac{3}{x ^{\frac{1}{4}}}
