It has to be in order of highest degree, degree is the exponents.

A. $xy^3 + 4x^5y + 10x^3$
B. $x^4y^2 + 4x^2y + 8x$
C. $-9x^4y^2 + 4x^3y^5 + 10x^2$
D. $x^6y^3 + 4x^4y^8 + x^2$

The degree of $xy^3$ is 4, because we add the exponents, x has an exponent of 1(you just don't see it) and y has an exponent of 3. 3 + 1 = 4

The next term has a degree of 6, because x has a 5, and y has a 1. 

5 + 1 = 6

First term = 4
Second term = 6

It has to be greatest to least, so A is incorrect.

Can you see which one is correct now?
