Question 934891
<pre>
When there are no plus signs (these things "+") then you can't be
talking about a SUM!  So I assumed you meant a PRODUCT, and posted
this:

{{{matrix(2,1,"",

1^(1/2)*2^(1/2)*3^(1/2)*""*""*n^(1/2) )}}}{{{matrix(2,1,"",""="")}}}{{{matrix(2,1,"",

(1*2*3*""*""*n)^(1/2) )}}}{{{matrix(2,1,"",""="")}}}{{{matrix(2,1,"",n!^(1/2))}}}{{{matrix(2,1,"",""="")}}}{{{matrix(2,1,"",sqrt(n!))}}}

If you REALLY meant a sum, then repost putting in some plus signs.
When there are no plus signs between things, everybody assumes 
they are to be multiplied, not added.
