Find the Degree 4xy^3-5xy^3+9x^2y

$4 x y^{3} - 5 x y^{3} + 9 x^{2} y$

Step 1

Subtract $5 x y^{3}$ from $4 x y^{3}$ .

$- x y^{3} + 9 x^{2} y$

Step 2

Identify the exponents on the variables in each term, and add them together to find the degree of each term.

$- x y^{3} \to 4$

$9 x^{2} y \to 3$

Step 3

The largest exponent is the degree of the polynomial.

$4$
