If the degree of (7x^m+2x^{10}+3) is (10) and (m<10), which value of (m) is possible?

Answer and explanation

Correct answer: \(m=8\)

The degree of a polynomial is the highest power of its variable. The term \(2x^{10}\) is already present. Since \(m<10\), taking \(m=8\) keeps \(10\) as the highest exponent, so the polynomial has degree \(10\). Although \(m=10\) would also leave the degree as 10, it does not satisfy the condition \(m<10\). Exam tip: While finding a degree, always check any condition given on the exponent as well.
