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

- \frac{4}{x}

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

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

Simplify

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

= - \frac{4}{x}
