= [\frac{1}{2} (x^{2} ln (x^{3}) - 2 \cdot \int \frac{3 x}{2} d x)]_{e}^{2 e}

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

= [\frac{1}{2} (x^{2} ln (x^{3}) - 2 \cdot \frac{3 x ^{2}}{4})]_{e}^{2 e}

Vereinfache

[\frac{1}{2} (x^{2} ln (x^{3}) - 2 \cdot \frac{3 x ^{2}}{4})]_{e}^{2 e} : [\frac{1}{2} (3 x^{2} ln (x) - \frac{3 x ^{2}}{2})]_{e}^{2 e}

= [\frac{1}{2} (3 x^{2} ln (x) - \frac{3 x ^{2}}{2})]_{e}^{2 e}
