integral of (3x+1)/(x^{2/3)}

Lösung

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

Lösung

\frac{9}{4} x^{\frac{4}{3}} + 3 x^{\frac{1}{3}} + C

Schritte zur Lösung

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

Multipliziere aus

\frac{3 x + 1}{x ^{\frac{2}{3}}} : 3 x^{\frac{1}{3}} + \frac{1}{x ^{\frac{2}{3}}}

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

\int 3 x^{\frac{1}{3}} d x = \frac{9}{4} x^{\frac{4}{3}}

\int \frac{1}{x ^{\frac{2}{3}}} d x = 3 x^{\frac{1}{3}}

= \frac{9}{4} x^{\frac{4}{3}} + 3 x^{\frac{1}{3}}

Füge eine Konstante zur Lösung hinzu

= \frac{9}{4} x^{\frac{4}{3}} + 3 x^{\frac{1}{3}} + C
