write each expression without using the factorial symbol.
1)(n3)!

n!
2) (n+4)!

(n+2)!

I will do one. Take the greater number, and expand it. for instance, the first
(n3)!/(n*(n1)(n2)(n3)!)
the (n3)! terms divide out..
1/(n)(n1)(n2) 
then the second one would be
(n+4)!/((n+1)(n+2)(n+3)(n+4)(n+2)!)
=
1/(n+1)(n+2)^2 (n+3) ?
