AFQT practice question: Mathematics Knowledge (MK)

Mathematics Knowledge (MK)Difficulty 2/5

What is (2³)² × 2⁻²?

  1. A64
  2. B8
  3. C16
  4. D32
Show answer and rationale

Correct: C. Power of a power multiplies exponents: (2³)² = 2⁶ = 64. Multiplying by 2⁻² subtracts 2 from the exponent: 2⁴ = 16.

  • B — 8 = 2³, missing the square.
  • D — 32 = 2⁵.
  • A — 64 = 2⁶, ignoring the 2⁻² factor.
