Question

The polynomial 9x^2+3x^3y^2z is what degree

Answer 1

You need to look at the powers of x, y and z and choose the highest one. That determines the degree of he poly. Here I see that the highest power of any of these three variables is x^3. Thus, the degree of this poly is 3.

9x^2+3x^3y^2z

Answer 2

3rd degree polynomial
