What is the total degree of (x^7y^2+x^5y^8+xy)?

Answer and explanation

Correct answer: 13

For a term in two variables, the total degree is the sum of the exponents of its variables. Here, the total degrees of x^7y^2, x^5y^8, and xy are 7+2=9, 5+8=13, and 1+1=2 respectively. The greatest of these is 13, so the total degree of the polynomial is 13. Option A is only the total degree of the first term. Exam tip: Find the total degree of every term and choose the greatest one.
