Multipliziere aus

\frac{x ^{2} + 3}{x} : x^{\frac{3}{2}} + \frac{3}{x}

= \int x^{\frac{3}{2}} + \frac{3}{x} d x

Wende die Summenregel an:

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

= \int x^{\frac{3}{2}} d x + \int \frac{3}{x} d x

\int x^{\frac{3}{2}} d x = \frac{2}{5} x^{\frac{5}{2}}

\int \frac{3}{x} d x = 6 x

= \frac{2}{5} x^{\frac{5}{2}} + 6 x
