hi Karimazer1



cancel x^(n-1)



Hope that helps.

Bob

ps.  Not very confident about expectation algebra.  Hopefully someone else is.  If you are still waiting for a reply to your other posts in 48 hours, post again and I'll try to help.  eek

I may have done something wrong along the way SO i moved a step back

We have

x - ((1/(x^N-1))*((x^N)/N)

I beg for your time on this, it hopefully isn't too long.

So the two things on the right hand side are multiplied and subtracted from x.

Somehow this is rewritten to equal

((N-1)/N)x


please help

So I have

N=1........n

x1 - x1/N

now somehow this EQUALS ((N-1)/N)*x1

can someone please explain how/why? thank you
