The standard form of the polynomial function is [tex]-6m^6+n^6+7mn^5+14m^2n^4-5m^3n^3[/tex].
The polynomial given is
[tex]8mn^5-2m^6+5m^2n^4-m^3n^3+n^6-4m^6+9m^2n^4-mn^5-4m^3n^3[/tex]
Let us rearrange the expression as,
[tex]-2m^6-4m^6+n^6+8mn^5-mn^5+5m^2n^4+9m^2n^4-m^3n^3-4m^3n^3[/tex]
Simplifying the above expression as,
[tex]-6m^6+n^6+7mn^5+14m^2n^4-5m^3n^3[/tex]
The above expression of the polynomial function is in its standard form.
Hence, the standard form of the polynomial function is [tex]-6m^6+n^6+7mn^5+14m^2n^4-5m^3n^3[/tex].
