integral of (ln^8(x))/x

\int \frac{ln ^{8} ( x )}{x} d x

\frac{ln ^{9} ( x )}{9} + C

Solution steps

\int \frac{ln ^{8} ( x )}{x} d x

Apply u-substitution

: \int u^{8} d u

= \int u^{8} d u

Apply the Power Rule

: \frac{u ^{9}}{9}

= \frac{u ^{9}}{9}

Substitute back

u = ln (x)

= \frac{ln ^{9} ( x )}{9}

Add a constant to the solution

= \frac{ln ^{9} ( x )}{9} + C

6 x^{- 4} + 5 x^{- 2}

\int ln (e^{x}) d x

\int \frac{ln ( n )}{n}

\frac{d y}{d x} = x \cdot y + \frac{x}{y}

\int_{1}^{16} x^{\frac{1}{2}} ln (x) d x
