Abstract

Sum of the powers of a natural number is proved pictorially via a one-dimensional modification of the two- and three-dimensional representations proposed by Mukherjee in a past study. As examples, sum of the powers of 4 and sum of the powers of 8 are illustrated by drawing an array of rectangles. These diagrams can be regarded as reflecting the self-similarity of the geometric structures of the above-mentioned sums.
