integral of (sqrt(x)+2ln(x))/x

\int \frac{x + 2 ln ( x )}{x} d x

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

Solution steps

\int \frac{x + 2 ln ( x )}{x} d x

Expand

\frac{x + 2 ln ( x )}{x} : \frac{1}{x} + \frac{2 ln ( x )}{x}

= \int \frac{1}{x} + \frac{2 ln ( x )}{x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{x} d x + \int \frac{2 ln ( x )}{x} d x

\int \frac{1}{x} d x = 2 x

\int \frac{2 ln ( x )}{x} d x = ln^{2} (x)

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

Add a constant to the solution

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