If 
is an integer, you can use induction. First show the inequality holds for 
. You have 
, which is true.
Now assume this holds in general for
, i.e. that 
. We want to prove the statement then must hold for 
.
Because, you have
and this must be greater than
for the statement to be true, so we require
for
. Well this is obviously true, because solving the inequality gives 
. So you're done.
If you is any real number, you can use derivatives to show that 
increases monotonically and faster than .
Now assume this holds in general for
Because
and this must be greater than
for
If you

Tom could pick Pants 1 (P1), then Sweater 1, 2 or 3. So 3 combinations
Similarly if we picked P2, P3, P4 or P5 we would have 3 combinations per each.
In total we have 5*3=15 different combinations.
Answer:15
