Answer:

C. x = 8

Step-by-step explanation:

We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.

Let's multiply 6 x 6 x 6.

36 x 6 = 216.

Let's multiply 8 x 8 x 8.

64 x 8 = 512

The answer would be C. x = 8.

I hope that this helps! :)
