If the degree of (3x^m+4x^6-1) is (6) and (m<6), which value of (m) is possible?

Answer and explanation

Correct answer: \(m=4\)

The degree of a polynomial is the greatest exponent of its variable. The term \(4x^6\) makes the degree 6. Since \(m<6\), \(m=4\) is possible, and the exponent in \(3x^4\) remains less than 6. Although \(m=6\) would not change the highest exponent, it does not satisfy \(m<6\); \(m=7\) and \(m=8\) would make the degree 7 or 8. Exam tip: In degree questions, first identify the highest exponent and then check every given condition.
