Schritte zur Lösung

\int_{4}^{8} ln (x^{2}) d x

Wende die partielle Integration an

= [x ln (x^{2}) - \int 2 d x]_{4}^{8}

\int 2 d x = 2 x

= [x ln (x^{2}) - 2 x]_{4}^{8}

Wende log Regel an

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x),

angenommen

x \geq 0

= [2 x ln (x) - 2 x]_{4}^{8}

Berechne die Grenzen:

32 ln (2) - 8

= 32 ln (2) - 8
