derivative of

\frac{1}{x + 3}

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

Solution steps

\frac{d}{d x} (\frac{1}{x + 3})

Apply exponent rule:

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

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

Apply the chain rule:

- \frac{1}{2 ( x + 3 ) ^{\frac{3}{2}}} \frac{d}{d x} (x + 3)

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

\frac{d}{d x} (x + 3) = 1

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

Simplify

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