derivative of 3/(3x-5)

Solution

\frac{d}{d x} (\frac{3}{3 x - 5})

Solution

- \frac{9}{( 3 x - 5 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{3}{3 x - 5})

Take the constant out:

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

= 3 \frac{d}{d x} (\frac{1}{3 x - 5})

Apply exponent rule:

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

= 3 \frac{d}{d x} ((3 x - 5)^{- 1})

Apply the chain rule:

- \frac{1}{( 3 x - 5 ) ^{2}} \frac{d}{d x} (3 x - 5)

= - \frac{1}{( 3 x - 5 ) ^{2}} \frac{d}{d x} (3 x - 5)

\frac{d}{d x} (3 x - 5) = 3

= 3 (- \frac{1}{( 3 x - 5 ) ^{2}} \cdot 3)

Simplify

3 (- \frac{1}{( 3 x - 5 ) ^{2}} \cdot 3) : - \frac{9}{( 3 x - 5 ) ^{2}}

= - \frac{9}{( 3 x - 5 ) ^{2}}
