Hi You can see it works for i.e. Now assume it is true for some Write: (by induction hypothesis) Can you end?
Thank you, but I cant end till I see. Once I see it I can solve another problem. I would appreciate if ou can end it.
Well the idea is to factorize by which appears in the two terms: which is what you wanted.
