Find the degree of the polynomial: - 3x^3y^3+2.5xz^2-5xz^2

Degree is 6

Step-by-step explanation:

Solving given polynomial gives - 3x^3y^3-2.5xz^2

as this polynomial involves two variables so we'll add the powers on variables in each term

first term: - 3x^3y^3, add powers on x and y variables which turns out to be 6

Second term: 2.5xz^2, adding powers on x and z variable results in 3

As degree is the highest power among different powers on terms so here the degree is 6
