Answer:
A. x = 3
Step-by-step explanation:
The question is;

To solve it, one has to do;
![x = \sqrt[3]{27}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B27%7D)
(x equals the cube root of 27)
The cube root essentially asks, what number times itself three times equals the number under the radical.
3 times itself 3 times equals 27, hence the answer is 3.
