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

Answer and explanation

Correct answer: 11

Find the total degree of each term: \(x^6y^2\) has degree \(6+2=8\), \(x^4y^7\) has degree \(4+7=11\), and \(xy\) has degree \(1+1=2\). The greatest of these is 11, so the total degree of the polynomial is 11. Option 8 is only the degree of the first term, not of the whole polynomial. Exam tip: For a polynomial in more than one variable, add the exponents in each term and select the greatest sum.
