192

Schritte zur Lösung

\int_{0}^{4} 9 x^{2} d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 9 \cdot \int_{0}^{4} x^{2} d x

Wende die Potenzregel an

= 9 [\frac{x ^{3}}{3}]_{0}^{4}

Berechne die Grenzen:

\frac{64}{3}

= 9 \cdot \frac{64}{3}

Vereinfache

= 192

\int_{0}^{y} \frac{6 ( y - x )}{8} d x

\int_{0}^{2} (2.5 - x^{2}) d x

\int_{0}^{1} π (4 - 4 x)^{2} d x

\int_{0}^{9} 2 x + 9 d x

\int_{0}^{1} x^{2} (2 x^{3} + 3)^{2} d x
