Show using the binomial theorem, that if then
Hereīs my brave attempt:
So at first I thougt that each term is bigger than one (this is the part that I got wrong). Then, since there are n terms, the sum must tend to infinity because n tends to infinity and since each term bigger than one.
The b part:
I want to try this myself after getting the a) part straight but I wonder is there a clue in the b part for solving a?
Any hints, besides replacing my toilet paper with my home assignment?
