Clue: There is a famous James-Stirling formula if you want to find out the number of digits it has...

Re: Math Help
A good computer probably wouldn't actually take too long to find the exact value of that, the problem is how it would display it to you.
9000! contains approximately 30000 digits.
Why did the vector cross the road?
It wanted to be normal.

and I bet like half of them are zeros

Re: Math Help

Re: Math Help
Ah, thanks guys. The problem for math simplified to 9000! Wasn't sure if I should solve it further or not.

I would guess that n! has very slightly less than n/4 zeroes.
Edit: Zeroes at the end, that is. There will be more scattered around the "interesting" part as well.

Re: Math Help
For any nonzero integer n and prime number p, we define
as the greatest integer r such that divides n.For every positive integer n and prime p
Example : 10!
therefore

Re: Math Help
While that makes small factorials look a bit nicer, I'm not sure how it would help out with 9000!.
You'd need a term for every prime between 1 and 9000, and there's probably around two thousand-ish of those so the expression would be a complete nightmare to write.
