Which expressions are equivalent to cube root of 128 to the x th power ? Choose three correct answers.

The cube root of 128 raised to the x power is (128^(1/3))^x, which equals 128^(x/3), so B is equivalent. Since 128 = 64 × 2, its cube root is 4∛2, making both C and D equivalent. A uses the exponent 3/x instead of x/3, and 2∛4 in E is not equal to ∛128.
