Answer 1

Hi, and welcome to QuestionCove!
The way the question is formatted is a bit confusing, but I think I understand the meaning
The expressions are 48m^5*n and 81m^2*n^2, yes?
In that case, the greatest common factor between the two expressions would be
3m^2*n, since this is the largest expression which can be multiplied by other integer expressions to get either of the original terms.
Please let me know if you would like a more detailed explanation, and best of luck in your studies :)
