A)2xy^3+3x^3y^4-4x^4y^5+9x^5y^6
B)8x^5-5y^4-2xy^5+x^2y
C)x^3y^2-3x^2y-9x^4y^3+11x
D)5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9

Answer 1

D).
`5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9`

Explanation:

For better clarity let us re write the options

A).
`2xy^3+3x^3y^4-4x^4y^5+9x^5y^6`

B).
`8x^5-5y^4-2xy^5+x^2y`

C).
`x^3y^2-3x^2y-9x^4y^3+11x`

D).
`5x^7y^2+7x^6y^5-14x^3y^7+51x^2y^9`

To express polynomial with mixed variables in standard form, we begin by the highest coefficient of x to the smallest (we place high precedence on the coefficient x terms)
