Please ignore - I got it.
Here is an outline of my approach
I proved that if and => and
Thus => k|2-1
Thanks
This is based on a earlier post on this forum only. Following lemma was used to solve a problem posted earlier - http://www.mathhelpforum.com/math-he...rs-155363.html
My question how do I prove this?
I have made an attempt but am stuck at this -
Given - Let m,n be any +ve integers. If a proposition is true for m and n then following holds true
1. proposition is true for (m+n)
2. proposition is true for (m-n), provided (m-n)>0
Claim - Proposition is true for all
am + bn, provided (am + bn) > 0, where a,b are any intergers (not necessarily >0)
How do I prove my claim? Some sort of induction?
Please help
