integral of 7x^{-2/3}-2x^{5/3}

Lösung

\int 7 x^{- \frac{2}{3}} - 2 x^{\frac{5}{3}} d x

21 x^{\frac{1}{3}} - \frac{3}{4} x^{\frac{8}{3}} + C

Schritte zur Lösung

\int 7 x^{- \frac{2}{3}} - 2 x^{\frac{5}{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 7 x^{- \frac{2}{3}} d x - \int 2 x^{\frac{5}{3}} d x

\int 7 x^{- \frac{2}{3}} d x = 21 x^{\frac{1}{3}}

\int 2 x^{\frac{5}{3}} d x = \frac{3}{4} x^{\frac{8}{3}}

= 21 x^{\frac{1}{3}} - \frac{3}{4} x^{\frac{8}{3}}
