What is the cube root of 8^2.
- 2
- 4
- 8
Explanation from PART66Online
First evaluate 8 squared, which is 64. The cube root of 64 is the number that cubed gives 64, and since 4 * 4 * 4 = 64, the answer is 4. The result is not 8 because the squaring and cube-rooting do not simply cancel here.

8^2=64,
√(64)^1/3 = 3^√64^1=4
√(64)^1/3 = 3^√64^1=4
