\frac{d}{d x} (\frac{7 x ^{2}}{x})

\frac{21 x}{2}

Solution steps

\frac{d}{d x} (\frac{7 x ^{2}}{x})

Simplify

\frac{7 x ^{2}}{x} : 7 x^{\frac{3}{2}}

= \frac{d}{d x} (7 x^{\frac{3}{2}})

Take the constant out:

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

= 7 \frac{d}{d x} (x^{\frac{3}{2}})

Apply the Power Rule:

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

= 7 \cdot \frac{3}{2} x^{\frac{3}{2} - 1}

Simplify

7 \cdot \frac{3}{2} x^{\frac{3}{2} - 1} : \frac{21 x}{2}

= \frac{21 x}{2}
