integral of (4sqrt(ln(x)))/x

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

\frac{8}{3} ln^{\frac{3}{2}} (x) + C

Solution steps

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

Take the constant out:

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

= 4 \cdot \int \frac{ln ( x )}{x} d x

Apply u-substitution

: \int u d u

= 4 \cdot \int u d u

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= 4 \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = ln (x)

= 4 \cdot \frac{2}{3} ln^{\frac{3}{2}} (x)

Simplify

4 \cdot \frac{2}{3} ln^{\frac{3}{2}} (x) : \frac{8}{3} ln^{\frac{3}{2}} (x)

= \frac{8}{3} ln^{\frac{3}{2}} (x)

Add a constant to the solution

= \frac{8}{3} ln^{\frac{3}{2}} (x) + C

\int (\frac{8}{5 x x ^{2} - 1}) d x

\int \frac{1}{x} + \frac{1}{x ^{2}} + \frac{1}{x ^{3}} + \frac{1}{x ^{4}} d x

\int \frac{sin ( arctan ( 2 x ) )}{1 + 4 x ^{2}} d x

\int \frac{- x - 2}{x ^{2} + 1} d x

\int (x - 2) e^{- x} d x
