Schritte zur Lösung

\int_{3}^{4} x + 7 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_{3}^{4} x d x + \int_{3}^{4} 7 x^{2} d x

\int_{3}^{4} x d x = \frac{7}{2}

\int_{3}^{4} 7 x^{2} d x = \frac{259}{3}

= \frac{7}{2} + \frac{259}{3}

Vereinfache

\frac{7}{2} + \frac{259}{3} : \frac{539}{6}

= \frac{539}{6}
