derivative of 5/(7x^2)

Solution

\frac{d}{d x} (\frac{5}{7 x ^{2}})

Solution

- \frac{10}{7 x ^{3}}

Solution steps

\frac{d}{d x} (\frac{5}{7 x ^{2}})

Take the constant out:

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

= \frac{5}{7} \frac{d}{d x} (\frac{1}{x ^{2}})

Apply exponent rule:

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

= \frac{5}{7} \frac{d}{d x} (x^{- 2})

Apply the Power Rule:

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

= \frac{5}{7} (- 2 x^{- 2 - 1})

Simplify

\frac{5}{7} (- 2 x^{- 2 - 1}) : - \frac{10}{7 x ^{3}}

= - \frac{10}{7 x ^{3}}
