If the degree of 2x^n + 7x^8 − 1 is n and n > 8, which value of n is possible?

Answer and explanation

Correct answer: n = 11

The governing concept is that the degree of a polynomial is the greatest exponent of a term with a nonzero coefficient. In 2x^n + 7x^8 − 1, the coefficient of x^n is 2, so the term cannot disappear. Since n > 8, the exponent n is greater than the exponent 8, and the degree is consequently n. We only need to identify which option is strictly greater than 8. The value 11 satisfies the condition. Values 6 and 4 are less than 8, while 8 is equal to 8 and does not satisfy the strict inequality n > 8. Therefore n = 11 is the only possible value, making option C correct. The constant term −1 has degree 0 and does not affect the comparison of the leading exponents.
