Question

what is the degree of 4x^2y+3xy^2+9xy​

Answer 1

Answer:

For a multivariable polynomial, it the highest sum of powers of different variables in any of the terms in the expression. Take following example, x5+3x4y+2xy3+4y2-2y+1. It is a multivariable polynomial in x and y, and the degree of the polynomial is 5 – as you can see the degree in the terms x5 is 5, x4y it is also 5 (4+1) and so the highest degree among these individual terms is 5.

A polynomial of two variable x and y, like axrys is the algebraic sum of several terms of the prior mentioned form, where r and s are possible integers. Here, the degree of the polynomial is r+s where r and s are whole numbers.

Note: Exponents of variables of a polynomial .i.e. degree of polynomials should be whole numbers.
