What is the total degree of (7x^5y^4-2x^3y^7+6xy^2-11)?

Answer and explanation

Correct answer: 10

The total degree of a multivariable polynomial is the greatest sum of the exponents of the variables in any one term. Here, the term degrees are 5+4=9, 3+7=10, 1+2=3, and 0 for the constant term -11. Therefore, the highest total degree is 10. Option 9 is the degree of the first term, not of the whole polynomial. Exam tip: Add the exponents in each term and select the largest sum.
