there is no such thing as "solving" either of those expressions, since they are not problems.
if you are talking about finding the actual numerical values -- like the value 24 for 4!, for instance -- then, obviously, you won't have to do that for such large expressions. the GMAT exam is not an exercise in pointless tedious manual arithmetic.
