No crash on my system.
(* With symbol infinity misspelled *)
In[1]:=
Limit[(((-2^(n - 1))*M)/(n!*L^(n - 1)))^(n/2), n -> infinity]
Out[1]=
-1 + infinity 1 - infinity
2 L M infinity/2
(-(------------------------------))
Gamma[1 + infinity]
(* With correct syntax *)
In[2]:=
Limit[(((-2^(n - 1))*M)/(n!*L^(n - 1)))^(n/2), n -> Infinity]
Out[2]=
0
In[3]:=
$Version
Out[3]=
5.2 for Microsoft Windows (June 20, 2005)
