Which is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y + 2x3y4 + xy3?

Answer 1

The degree of the sum and difference of the polynomials 3x^5y - 2x^3y^4 - 7xy^3 and -8x^5y + 2x^3y^4 + xy^3 will be the same as the highest degree term in the polynomials, which is x^5y. So, the degree of the sum and difference of these polynomials is 5.
