\frac{d}{d x} (4 ln (5 x))

\frac{4}{x}

Solution steps

\frac{d}{d x} (4 ln (5 x))

Take the constant out:

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

= 4 \frac{d}{d x} (ln (5 x))

Apply the chain rule:

\frac{1}{5 x} \frac{d}{d x} (5 x)

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

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

= 4 \cdot \frac{1}{5 x} \cdot 5

Simplify

4 \cdot \frac{1}{5 x} \cdot 5 : \frac{4}{x}

= \frac{4}{x}

\frac{d}{d x} ((x - 4) e^{3 x})

e^{- 2 x}

x \to 0 lim (coth (x))

3 x^{2} + 4

\frac{1}{1 - x}
