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

\frac{18}{( 1 + 3 x ) ^{3}}

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

- 3 (- \frac{2}{( 1 + 3 x ) ^{3}} \cdot 3) : \frac{18}{( 1 + 3 x ) ^{3}}

= \frac{18}{( 1 + 3 x ) ^{3}}

(x^{2} - 2 x + 5) 25 - x^{2}

- 5 x^{\frac{1}{2}} + x^{\frac{3}{2}}

\int 3 x + \frac{1}{x} d x

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

\frac{d}{d x} (- e^{x y})
