State the degree: x^5y^2+7x^3y^7-3x^2y^4 Does that mean the highest =7 OR Does that mean adding 5+2+3+7+2+4=23

    i thing it means the highest degree of the polynomials.

    x^5y^2+7x^3y^3-3x^2y^4 : monomial x^5y^2+7x^3y^3-3x^2y^4=0 : polynomials I was told @hal_stirrup

    I have none @radar I could put 7 because it is the highest degree but i think x^5y^2+7x^3y^3-3x^2y^4 is a monomial so for that degree you add them toghether so 23

    so it would be 23? @hal_stirrup

    The determination of degree is dependent on the exponent of the variable terms. In your problem the x variable highest degree is 5 or fifth degree and it appears that is the highest for the x term, I am not sure how to handle when you have two different variables.

    I meant x^5y^2+7x^3y^7-3x^2y^4

    ok . what i think is correct is so: If there are three monomials or more, being added or subtracted, to make a polynomial, and each has a degree (lone variable has a degree of 1) and the monomial that has the highest degree represnts the whole polynomial's degree.

    so it would be 10 because 3+7

    With that infromation provided by hal_stirrup then it appears it would be a 10th degree expression.

    if your question asked you specifically for x variable or y variable then its the highs exponent degree of x or y..
