m and n are both integers, and m#n, does n = 0?
(1) m = 7
(2) mn = n^2
---------------------------
![]()
(1) m = 7
(2) mn = n^2
---------------------------

Got this question from a Kaplan advanced quant library. I don't understand why statement 2 is sufficient. I understand that m cannot be equal to n, however, how is n forced to be equaled to be 0? I haven't found a question similar to this in the OG yet. If you have similar questions, please post! Thanks
