Is there anybody can help me to get an expansion for the following finite Power Sum? (Sum[(\[Beta]*x)^i/i!, {i, 0, m - 1}])^n As I know the infinite power sum can be expressed as follows but what about the case of finite power sum? Thanks for your support

I get the following result using Mathematica 9: In[1]:= (Sum[(\[Beta]*x)^i/i!, {i, 0, m - 1}])^n Out[1]= ((E^(x \[Beta]) Gamma[m, x \[Beta]])/Gamma[m])^n S M Blinder

Thanks for your reply, but I need to get a result in summation form, and Not in Gamma function.
