What is the total degree of (8x^6y^4-3x^2y^9+5xy^3-7)?

Answer and explanation

Correct answer: 11

The total degree of a polynomial is the greatest sum of the exponents of the variables in any one term. The term degrees here are \(6+4=10\), \(2+9=11\), \(1+3=4\), and \(0\) for the constant term \(-7\). Hence, the highest total degree is \(11\). Although \(10\) is the degree of the first term \(8x^6y^4\), it is not the greatest. Exam tip: add the exponents within each term, then select the largest sum.
