Identify the degree of the polynomial 8x^3y^2 - 10xy + 4x^2y^2 + 3.

When the polynomial has more than one variable you have to sum the exponents of the variables for every monomial. The largest sum is the order of the polynomial.

Here:

momomial sum of the exponents

8x^3y^2 3 + 2 = 5

-10xy 1 + 1 = 2

4x^2y^2 2 + 2 = 4

Then the degree is 5.
