Answer

3

Work Step by Step

see: Rules for Limits Let $a, A$, and $B$ be real numbers, and let $f$ and $g$ be functions such that $\displaystyle \lim_{x\rightarrow a}f(x)=A$ and $\displaystyle \lim_{x\rightarrow a}g(x)=B$. 6. For any real number $k,\displaystyle \lim_{x\rightarrow a}[f(x)]^{k}=[\lim_{x\rightarrow a}f(x)]^{k}=A^{k}$, provided this limit exists. --------------- $\displaystyle \lim_{x\rightarrow 4}\sqrt[3]{g(x)}=\lim_{x\rightarrow 4}[g(x)]^{1/3}$ $=[\displaystyle \lim_{x\rightarrow 4}g(x)]^{1/3}$ $=27^{1/3}=3$
