[algogeeks] Re: Doubt with summation

[Allysson Costa]

I had made the substituition but I don't get to go back to 2i. n-2i=2m Then SUM[lg(2m)]= SUM [lg2+lgm]=SUM[lg2]+SUM[lgm]= SUM [1] +SUM[lgm] OBS: SUM = SUMMATION. I stop here. I dont know how to continue. Can you help me. Thanks in advance Allysson Ajinkya Kale escreveu: substitute n-2i = 2m in firsst equation....you will get the left one on reducing the terms in terms of m.   On 10/19/07, Allysson Costa <[EMAIL PROTECTED]> wrote: Anyone can give a explanation how I get the equation below true? Why lg(n-2i) became lg(2i)? Thanks in advance.
