which is equivalent to 216^{\frac{1}{3}}?\n3\n6\n36\n72
Answer
Explanation:
Step1: Recall exponent rule
The rule for $a^{\frac{1}{n}}$ is $\sqrt[n]{a}$. So $216^{\frac{1}{3}}=\sqrt[3]{216}$.
Step2: Find the cube - root
We need to find a number $x$ such that $x\times x\times x = 216$. Since $6\times6\times6=216$, $\sqrt[3]{216}=6$.
