+1

Dezimale

Schritte zur Lösung

\int_{3}^{7} x^{2} - 9 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}^{7} x^{2} d x - \int_{3}^{7} 9 d x

\int_{3}^{7} x^{2} d x = \frac{316}{3}

\int_{3}^{7} 9 d x = 36

= \frac{316}{3} - 36

Vereinfache

\frac{316}{3} - 36 : \frac{208}{3}

= \frac{208}{3}
