limit as x approaches 0+of x^3*ln(x)

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

0

Solution steps

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

Rewrite for L'Hopital

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

Apply L'Hopital's Rule

= x \to 0 + lim (\frac{\frac{1}{x}}{- \frac{3}{x ^{4}}})

Simplify

\frac{\frac{1}{x}}{- \frac{3}{x ^{4}}} : - \frac{x ^{3}}{3}

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

Plug in the value

x = 0

= - \frac{0 ^{3}}{3}

Simplify

- \frac{0 ^{3}}{3} : 0

= 0
