integral of 1/(x(ln(x))^4)

\int \frac{1}{x ( ln ( x ) ) ^{4}} d x

- \frac{1}{3 ln ^{3} ( x )} + C

Solution steps

\int \frac{1}{x ( ln ( x ) ) ^{4}} d x

Apply u-substitution

= \int \frac{1}{u ^{4}} d u

Apply the Power Rule

= - \frac{1}{3 u ^{3}}

Substitute back

u = ln (x)

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

Add a constant to the solution

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