RE: Little math problems September 2018
Using (2,2) as base, one general solution for square / cube puzzle:
Below equality work for all non-negative integer n: (26n+1)2 + (26n+1)2 = 212n+3 = (24n+1)3 (26n+1)3 + (26n+1)3 = 218n+4 = (29n+2)2 Edit: For *all* base (a,b), positive integer k, scale up k6 will work. So, Valentin big examples (post #7) automatically work, because base = (2,2): 9500208482 = 2 * 41^6 993962581922 = 2 * 89^6 7081411940532321969341507101262893738689268797761826852357921359507223378 = 2 * 1234567890123^6 Looking at above k = 1234567890123, seems Valentin already know this |
