limit as x approaches 0+of (x)ln(x^4)

x \to 0 + lim ((x) ln (x^{4}))

0

Solution steps

x \to 0 + lim (x ln (x^{4}))

ln (x^{4}) = 4 ln (x)

= x \to 0 + lim (x \cdot 4 ln (x))

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

= 4 \cdot x \to 0 + lim (x ln (x))

Rewrite for L'Hopital

= 4 \cdot x \to 0 + lim (\frac{ln ( x )}{\frac{1}{x}})

Apply L'Hopital's Rule

: x \to 0 + lim (\frac{\frac{1}{x}}{- \frac{1}{x ^{2}}})

= 4 \cdot x \to 0 + lim (\frac{\frac{1}{x}}{- \frac{1}{x ^{2}}})

Simplify

\frac{\frac{1}{x}}{- \frac{1}{x ^{2}}} : - x

= 4 \cdot x \to 0 + lim (- x)

Plug in the value

x = 0

= 4 (- 0)

Simplify

= 0

\frac{40}{1 + 25 p + 100 p ^{2}}

\frac{\partial}{\partial x} (x yz - sin (x + y + z))

\int 8 cot^{4} (x) d x

\frac{d}{d x} (x^{\frac{3}{2}} - 1)

\frac{d}{d x} (4 a sec (x) tan (x))
