Write in Standard Form 8mn^5-2m^6+5m^2n^4-m^3n^3+n^6-4m^6+9m^2n^4-mn^5-4m^3n^3

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

Subtract ${\displaystyle m{n}^5}$ from ${\displaystyle 8m{n}^5}$.

Subtract ${\displaystyle 4m^6}$ from ${\displaystyle -2m^6}$.

Add ${\displaystyle 5m^2{n}^4}$ and ${\displaystyle 9m^2{n}^4}$.

Subtract ${\displaystyle 4m^3{n}^3}$ from ${\displaystyle -m^3{n}^3}$.
