Factoring - Can this be reduces

[rad0786]

Is there anyway that I can REDUCE this any further:

(N^N)(N!)(N^2 - N)!
(N^2)!


This equation comes from (N^N)/(N^2 Choose N)

what is the formula for choose??

so in other words what is $C(N^2, N)$?
can u see how this can be used in the expression taht you need to simplify??
