GMAT Data Sufficiency (DS) | Re: If m and n are non-zero integers, is mn > nn?

Statement 1: it implies that n>0 (as mod cannot be negative) and "m" can be m>0 or m<0
if m>0, then m=n, somn = nn
if m<0, then m=-n,so mn<nn (as "mn" will be negative & "nn" will be positive)
In either case "mn" will not be greater than "nn". So a definite NO. Hence sufficient

Statement 2: we don't know whether "m" &
