If the degree of (5x^m+6x^7+2) is (7) and (m<7), which value of (m) is possible?

Answer and explanation

Correct answer: \(m=5\)

The degree of a polynomial is the greatest exponent of the variable having a non-zero coefficient. The term \(6x^7\) makes the degree 7. Since \(m<7\), \(m=5\) is possible, and the greatest exponent still remains 7. Although \(m=7\) would also keep the degree 7, it does not satisfy the given condition \(m<7\). Exam tip: compare all exponents and then check every stated condition separately.
