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

4 (ln (x) + 1)

Solution steps

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

Take the constant out:

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

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x, g = ln (x)

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

\frac{d x}{d x} = 1

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

= 4 (1 \cdot ln (x) + \frac{1}{x} x)

Simplify

4 (1 \cdot ln (x) + \frac{1}{x} x) : 4 (ln (x) + 1)

= 4 (ln (x) + 1)
