What is the cube root of 64x12?

4x4

4x6

8x4

8x6

As 64 is a perfect cube, the coefficient part does not present any problems. However, for the variable with an exponent, it is easier to obtain the cube root by multiplying the exponent by (1/3), since the cube root operator is equivalent to raising a number to the power of (1/3). This is shown below:

cube root (64x^12) = 4 * x^ (12) (1/3) = 4 * x^4

Therefore, the answer is 4x^4.
