Advanced Math practice question

Answer: 4

4³ = 4 · 4 · 4 = 64, so x = 4.

Common wrong answers

If you answered 8

8 is the square root of 64; the cube root is 4.

If you answered 16

16 is 64 ÷ 4, not a root of the equation.

If you answered 21.33

Dividing 64 by 3 is not taking a cube root; 4³ = 64.
