limit as x approaches 0 of ((x+64)^{1/3}-4)/x

x \to 0 lim (\frac{( x + 64 ) ^{\frac{1}{3}} - 4}{x})

\frac{1}{48}

Decimal

0.02083 \dots

Solution steps

x \to 0 lim (\frac{( x + 64 ) ^{\frac{1}{3}} - 4}{x})

Apply L'Hopital's Rule

= x \to 0 lim \frac{\frac{1}{3 ( x + 64 ) ^{\frac{2}{3}}}}{1}

Plug in the value

x = 0

= \frac{\frac{1}{3 ( 0 + 64 ) ^{\frac{2}{3}}}}{1}

Simplify

\frac{\frac{1}{3 ( 0 + 64 ) ^{\frac{2}{3}}}}{1} : \frac{1}{48}

= \frac{1}{48}
