Respuesta :

The degree of the sum and difference of the polynomials are 6 and 7 respectively.

given polynomials are:

[tex]3x^5-2x^3y^4-7xy^3[/tex]

[tex]-8x^5y+2x^3y^4+xy^3[/tex]

the sum of polynomials = [tex]-5x^5y-6xy^3[/tex]

the difference of polynomials = [tex]11x^5y-4x^3y^4-8xy^3[/tex]

what is the degree of a polynomial?

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

degree of sum = monomial with highest power = 5+1=6

degree of difference = monomial with highest power = 3+4 = 7

therefore, the degree of the sum and difference of the polynomials are 6 and 7 respectively.
