derivative of

- \frac{14}{( t + 15 ) ^{2}}

\frac{28}{( t + 15 ) ^{3}}

Solution steps

\frac{d}{d t} (- \frac{14}{( t + 15 ) ^{2}})

Take the constant out:

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

= - 14 \frac{d}{d t} (\frac{1}{( t + 15 ) ^{2}})

Apply exponent rule:

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

= - 14 \frac{d}{d t} ((t + 15)^{- 2})

Apply the chain rule:

- \frac{2}{( t + 15 ) ^{3}} \frac{d}{d t} (t + 15)

= - \frac{2}{( t + 15 ) ^{3}} \frac{d}{d t} (t + 15)

\frac{d}{d t} (t + 15) = 1

= - 14 (- \frac{2}{( t + 15 ) ^{3}} \cdot 1)

Simplify

- 14 (- \frac{2}{( t + 15 ) ^{3}} \cdot 1) : \frac{28}{( t + 15 ) ^{3}}

= \frac{28}{( t + 15 ) ^{3}}
