Schritte zur Lösung

x \to 0 + lim (x^{3} (ln (x))^{2})

Umformung für L'Hopital

= x \to 0 + lim (\frac{( ln ( x ) ) ^{2}}{\frac{1}{x ^{3}}})

Wende das L'Hopital Theorem an

= x \to 0 + lim (\frac{\frac{2 l n ( x )}{x}}{- \frac{3}{x ^{4}}})

Vereinfache

\frac{\frac{2 l n ( x )}{x}}{- \frac{3}{x ^{4}}} : - \frac{2}{3} x^{3} ln (x)

= x \to 0 + lim (- \frac{2}{3} x^{3} ln (x))

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= - \frac{2}{3} \cdot x \to 0 + lim (x^{3} ln (x))
