Re Mathematica 5.1 under WinXP Home.
When I enter Product[x^t[k], {k, 1, 3}] the result is as expected, x^(t[1]+t[2]+t[3]).
However, when the upper limit is the uninstantiated variable n, the output is the input itself, i.e., Product[x^t[k], {k, 1, n}].
What I want is x^Sum[t[k],{k,1,n}].
Although I can easily get this using patterns, is there a simpler way that uses some option (in Simplify or FullSimplify) or some other command?
Thanks.
Bruce
