Answer:
[tex]5xy + 7 {xy}^{4} - 6 {x}^{3} - 10000[/tex]
Step-by-step explanation:
[tex]3xy + 7 {xy}^{4} - 6 {x}^{3} + 2xy - 10 {xy}^{4} [/tex]
[tex]3xy + 2xy[/tex]
[tex] (3 + 2)xy = 5xy[/tex]
[tex]5xy + 7 {xy}^{4} - 6 {x}^{3} - {10}^{4} [/tex]
[tex] {10}^{4} = 10 \times 10 \times 10 \times 10 = 10000[/tex]
[tex]5xy + 7 {xy}^{4} - 6 {x}^{3} - 10000[/tex]
