integral of (ln(x^{38}))/x

\int \frac{ln ( x ^{38} )}{x} d x

19 ln^{2} (x) + C

Solution steps

\int \frac{ln ( x ^{38} )}{x} d x

Apply u-substitution

= \int \frac{ln ( u )}{38 u} d u

Take the constant out:

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

= \frac{1}{38} \cdot \int \frac{ln ( u )}{u} d u

Apply u-substitution

= \frac{1}{38} \cdot \int v d v

Apply the Power Rule

= \frac{1}{38} \cdot \frac{v ^{2}}{2}

Substitute back

= \frac{1}{38} \cdot \frac{ln ^{2} ( x ^{38} )}{2}

Simplify

\frac{1}{38} \cdot \frac{ln ^{2} ( x ^{38} )}{2} : 19 ln^{2} (x)

= 19 ln^{2} (x)

Add a constant to the solution

= 19 ln^{2} (x) + C
