derivative of x*(ln(x)^2)

Solution

\frac{d}{d x} (x \cdot (ln (x))^{2})

Solution

ln^{2} (x) + 2 ln (x)

Solution steps

\frac{d}{d x} (x (ln (x))^{2})

Apply the Product Rule:

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

f = x, g = (ln (x))^{2}

= \frac{d x}{d x} (ln (x))^{2} + \frac{d}{d x} ((ln (x))^{2}) x

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

\frac{d}{d x} ((ln (x))^{2}) = \frac{2 ln ( x )}{x}

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

Simplify

1 \cdot ln^{2} (x) + \frac{2 ln ( x )}{x} x : ln^{2} (x) + 2 ln (x)

= ln^{2} (x) + 2 ln (x)
