\frac{7 + x + x}{x} : \frac{7}{x} + \frac{1}{x} + 1

= \int \frac{7}{x} + \frac{1}{x} + 1 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 \frac{7}{x} d x + \int \frac{1}{x} d x + \int 1 d x

\int \frac{7}{x} d x = 7 ln ∣ x ∣

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

\int 1 d x = x

= 7 ln ∣ x ∣ + 2 x + x
