An algebra problem by Vivek DhimanAlgebra Level 3
If you try to fold a paper multiple times in half and diagonally every time, you won't be able to fold it further after 7-8 folds. May be 10-12 folds if you have a really big sheet of paper. Now lets assume that you can fold it as many times as you want. If the thickness of the folded paper is 1 cm after 8 folds, then calculate the thickness of it after 50 folds. But before calculating, try and guess a number and then see the difference between your guess and the actual number.
