To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
![\sqrt[3]{216 x^(27) }](https://img.qammunity.org/2019/formulas/mathematics/middle-school/at3bxovadfhykvvb6z6qay722gybcqsacu.png)
2. Rewriting the expression we have:
![\sqrt[3]{6^3 x^(27) }](https://img.qammunity.org/2019/formulas/mathematics/middle-school/8it5mfwhlod01tgt1z6837f8p8hmjsf0hn.png)
3. You have that

and the exponent

are divisible by index

. Therefore, you have:
![\sqrt[3]{216 x^(27) } =6 x^(9)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/j4bysjj5szxgx0hqkhjymryhpkcgzwbqmf.png)
Therefore, as you can see,
the answer is the option, which is:
