Hi Jonask. Thanx for the help, I appreciate. I think I am giving over the question wrong, Its a GRE question. They give two values 1/2^1-k and then 1/8 in the question. Then they give two possible answers for which they want to know what answer is the biggest, k or -2?  Does that explain it better?
