What is the degree of the polynomial - 2xy^5 + 3x^7 - 10x^3y^6 ^+8x^6+4

We have the following polynomial:

- 2xy ^ 5 + 3x ^ 7 - 10x ^ 3y ^ 6 + 8x ^ 6 + 4

The degree of a polynomial is the same as the degree of the term with the highest degree.

We have then that the highest degree is in the following term:

10x ^ 3y ^ 6 = 3 + 6 = 9

Answer:

The polynomial is degree 9.
