Difference of Two CubesA (rather too short) page on the Difference of Two Cubes "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20090824 20:13:48
Re: Difference of Two CubesHi MathsisFun; It does some nifty expansions like: calling a= 5x and b =2 So numbers like 15617 which equal 25^3  2^3 can be factored but not always into primes. 15617 = (23)(679) In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
