If the degree of (6x^m+3x^9+5) is (9) and (m<9), which value of (m) is possible?

Answer and explanation

Correct answer: \(m=7\)

The degree of a polynomial is the highest power of the variable with a non-zero coefficient. Since the term \(3x^9\) is present and \(m<9\), the power in \(6x^m\) must be less than 9. For \(m=7\), the highest power is still \(9\), so the degree remains \(9\). Although \(m=9\) would also give degree 9, it does not satisfy \(m<9\). Exam tip: While finding degree, always check any condition given on the exponent as well.
