Question 4 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY
Use the exponent rules to simplify each expression. A has exponent −10 − (−7) = −3, B has exponent 4 − 0 = 4, C has exponent (5 − 2) × 2 = 6, and D has exponent (5 − 4) × (−2) = −2. The highest final exponent is 6, so the correct choice is C, the expression with exponent 6.
