Re: How do I solve this?

I'm tryign to solve the following two equations by >eliminating N.

http://img504.imageshack.us/img504/8241/22908111ca8.jpg

My guess is that r can be considered to be 2 for this >case. otherwise
i can't think of anyways to solve one of the equations >for N.

Is there?

I thought I would raise both sides of equation 1, to the >power of r.
then Collect and solve for N...

So how do you solve ( C_m / ( 1 + N^r ) ) ^ r for N?

Or what does it mean to to say ( 1 + N^r ) ^ r when the >values of r
is unknown?

Any tips are welcome.


Hi,

you could divide the left-hand side of (1) through the
left-hand side of (2) and the right-hand side of (1)
through the right-hand side of (2) to arrive at

(1 + N^r) / r = N*r/C_n * (C_n/N - 1)

which (for r = 2) results in a quadratic equation for N.

Best wishes
Torsten.
