Advanced Math practice question

Answer: 5

12 ÷ 4 = 3 and x³ ÷ x = x², so k = 3, n = 2, and k + n = 5.

Common wrong answers

If you answered 4

4 uses n = 1.

If you answered 6

6 uses n = 3, forgetting to subtract the exponent of x in the denominator.

If you answered 11

11 uses k = 8 (12 − 4) instead of 12 ÷ 4.
