Webthe Sum of Two Cubes Kevin A. Broughan University of Waikato, Hamilton 2001, New Zealand, [email protected] Abstract. A computational approach to finding an intrinsic character-ization of integers which are cube free and can be expressed as the sum of two cubes, n = x3 +y3, is developed. Every n has a multiple which is a sum of two cubes. Web1 Try expanding ( p + q + r) 3 and ( p q + p r + q r) ( p + q + r) and see if anything comes to mind. You should be able to retrieve p 3 + q 3 + r 3 from there.
