Can this be simplified any further?

M's cancel out. Year 7 linear algebra dude

>>7926701
[math]1-im^{-1}[/math]

>>7926701 (OP)
Well you can write it as :
[eqn] \frac{m!}{m^n} [/eqn]

But for actual simplification you need to know the prime decomposition of m.
If m is prime, you can't simplify.

Sorry should be :
[eqn] \frac{m!}{m^n n!} [/eqn]

>>7927093
pretty sure that's wrong lol

>>7926701
No.

>>7927609
It's not. If you're sure I'm wrong then you'll have no problem finding a counter example.

>>7930250
Not him, but do you mind proving it?

>>7926708
>>7926714
That's not simplified you fucking retards

>>7927093
The bottom factorial should be [math](m-n)![/math].

>>7926701
(M-1)!/(n!×m)

Ah yes sorry, you're right.
