Answer: The difference is,
[tex]m^2n^2-mn-11[/tex]
Step-by-step explanation:
Given expression is,
[tex](m^2n^2-7)-(mn+4)[/tex]
By distributive property,
[tex]m^2n^2-7-mn-4[/tex]
Combine like terms( that have the same variables and powers ),
[tex]m^2n^2-mn-11[/tex]
Which is the required result.
Hence, option third is correct.
