integral of (2sqrt(x^3)+7\sqrt[3]{x^2})

Lösung

\int (2 x^{3} + 7 3 x^{2}) d x

\frac{4}{5} x^{\frac{5}{2}} + \frac{21}{5} x^{\frac{5}{3}} + C

Schritte zur Lösung

\int 2 x^{3} + 7 3 x^{2} 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 2 x^{3} d x + \int 7 3 x^{2} d x

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

\int 7 3 x^{2} d x = \frac{21}{5} x^{\frac{5}{3}}

= \frac{4}{5} x^{\frac{5}{2}} + \frac{21}{5} x^{\frac{5}{3}}

= \frac{4}{5} x^{\frac{5}{2}} + \frac{21}{5} x^{\frac{5}{3}} + C

\int 3 + 2 x - x^{2} d x

\int 2 x sin (x) cos (x) d x

\int (x^{5} - 9 x)^{2} (5 x^{4} - 9) d x

\int \frac{x ( 1 + x ^{2} )}{1 + x ^{4}} d x

\int e^{3 s + 9} d s
