integral of ((x+sqrt(x))^2+8e^{2x})

Lösung

\int ((x + x)^{2} + 8 e^{2 x}) d x

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

Schritte zur Lösung

\int (x + x)^{2} + 8 e^{2 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 + x)^{2} d x + \int 8 e^{2 x} d x

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

\int 8 e^{2 x} d x = 4 e^{2 x}

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