Suppose that you calculate a number with the form x^y, where x = 999...999 and y is a natural number. If you arrange it as the shape of a rectangle whose width is the number of the digits of x, then you get a beautiful figure. This fact has been already published as R.Miyadera, D.Minematsu and S.Hashiba, A beautiful figure made of 999...9^n, Visual Mathematics , Vol 6, No.2, 2006, Mathematical Institute of the Serbian Academy of Sciences and Arts.
