derivative of 1/((x+7^2))

Solution

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

Solution

- \frac{2}{( x + 7 ) ^{3}}

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

\frac{d}{d x} (x + 7) = 1

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

Simplify

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