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

Answer and explanation

Correct answer: 5

Find the total degree of each term: \(4x^2y^3\) has degree \(2+3=5\), \(-3xy^2\) has degree \(1+2=3\), and the constant term \(9\) has degree \(0\). The greatest of these is \(5\), so the total degree of the polynomial is \(5\). Option 3 is the degree of the second term, not of the whole polynomial. Exam tip: for a polynomial in several variables, add the exponents in each term and select the greatest sum.
