integral of 3((ln(x))^2)/x

\int 3 \frac{( ln ( x ) ) ^{2}}{x} d x

ln^{3} (x) + C

Solution steps

\int 3 \cdot \frac{( ln ( x ) ) ^{2}}{x} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 3 \cdot \int \frac{( ln ( x ) ) ^{2}}{x} d x

Apply u-substitution

= 3 \cdot \int u^{2} d u

Apply the Power Rule

= 3 \cdot \frac{u ^{3}}{3}

Substitute back

u = ln (x)

= 3 \cdot \frac{ln ^{3} ( x )}{3}

Simplify

3 \cdot \frac{ln ^{3} ( x )}{3} : ln^{3} (x)

= ln^{3} (x)

Add a constant to the solution

= ln^{3} (x) + C
