What is the total degree of (x^4y^2+x^2y^5+xy)?

Answer and explanation

Correct answer: 7

Find the total degree of each term: \(x^4y^2\) has degree \(4+2=6\), \(x^2y^5\) has degree \(2+5=7\), and \(xy\) has degree \(1+1=2\). The greatest of these is 7, so the total degree of the polynomial is 7. Option 6 is only the degree of the first term. Exam tip: For a term with two or more variables, add their exponents and then choose the greatest such sum.
