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

Answer and explanation

Correct answer: 9

For a polynomial in several variables, the total degree is the greatest sum of exponents in any one term. The term \(x^2y^3z^4\) has total degree \(2+3+4=9\). The term \(3xy^2z\) has total degree \(1+2+1=4\), while the constant \(-5\) has degree 0. Hence, the greatest total degree is 9. Exam tip: add the exponents within each term and choose the largest sum; do not multiply the exponents.
