Advanced Math practice question
The expression 12x⁵ / (4x²) simplifies to axⁿ, where a and n are constants. What is the value of a·n?
Answer: 9
12/4 = 3 and x⁵/x² = x³, so a·n = 3 × 3 = 9.
Common wrong answers
- If you answered 3
- 3 is a alone, or n alone.
- If you answered 30
- 30 uses n = 10, multiplying the exponents.
- If you answered 7.5
- 7.5 uses n = 2.5, dividing the exponents.
