If the degree of (4x^n+3x^8-1) is (n) and (n>8), which value of (n) is possible?

Answer and explanation

Correct answer: \(n=9\)

Since \(n>8\), the power \(n\) in the term \(4x^n\) is greater than 8. Thus, \(4x^n\) is the highest-degree term, and the degree of the polynomial is \(n\). Among the given choices, only \(n=9\) satisfies \(n>8\). Although \(n=8\) is the closest value, it does not satisfy the strict inequality. Exam tip: when finding degree, identify the greatest exponent and check every stated condition carefully.
