Hello-(adsbygoogle = window.adsbygoogle || []).push({});

I have posted this question in Calculus before, but somebody pointed out that it is basic arithmetic and so I will post it here because of the error hoping I will get a fast reply:

I have a summation, and need to get the constantCout so that I can eleminate it at a later stage when dividing by a similar summation with the same C. Here it is:

[itex]\sum^{N}_{t=1}[/itex][itex]\beta^{t}[/itex][itex]\frac{C(1-g)^{t}-1}{1-\alpha}[/itex]

Where α,β, and C are all constants and I am interested in getting C out.

Of course, the above problem can be equivalent to the problem of getting C out in the following equation:

[itex]\sum^{N}_{t=1}[/itex][itex]\beta^{t}C-\beta^{t}[/itex]

with something like [itex]C\sum^{N}_{t=1}[/itex]...... , that is just one Ʃ.

any ideas?

Thanks
