Degrees of Multivariable Polynomials Examples

What's the degree of the following multivariable polynomial?

4x² + 3x²y – 5xy⁴ +7y – 9

Let's look at the degree of each term:

The largest degree of any term is 5, so the degree of the polynomial is 5. Done and done. Didn't even break a sweat.

Determine the degree of each term of the polynomial 5xy² + 3x⁶y⁴ + 7y⁹.
