For x ≠ 0, which expression is equivalent to (x²)⁴?
- A. x⁸Correct
- B. x⁶
- C. x¹⁶
- D. x²
Answer: A. x⁸
A power of a power multiplies exponents: 2 · 4 = 8.
Why the other answers are wrong
- B. x⁶
- x⁶ adds the exponents; the power-of-a-power rule multiplies them.
- C. x¹⁶
- x¹⁶ squares the 4 (or treats the rule as 2⁴); the product 2 · 4 is 8.
- D. x²
- x² ignores the outer exponent entirely.
