integral of 1/((xln(x^3)))

\int \frac{1}{( x ln ( x ^{3} ) )} d x

\frac{1}{3} ln (3 ∣ ln (x) ∣) + C

Solution steps

\int \frac{1}{x ln ( x ^{3} )} d x

Apply u-substitution

= \int \frac{1}{3 u ln ( u )} d u

Take the constant out:

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

= \frac{1}{3} \cdot \int \frac{1}{u ln ( u )} d u

Apply u-substitution

= \frac{1}{3} \cdot \int \frac{1}{v} d v

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= \frac{1}{3} ln ∣ v ∣

Substitute back

= \frac{1}{3} ln ln (x^{3})

Simplify

\frac{1}{3} ln ln (x^{3}) : \frac{1}{3} ln (3 ∣ ln (x) ∣)

= \frac{1}{3} ln (3 ∣ ln (x) ∣)

Add a constant to the solution

= \frac{1}{3} ln (3 ∣ ln (x) ∣) + C
