| Oct 15, 2014 at 19:56 | comment | added | Otaia | @SQB The problem states that the numbers come out in reverse order, beginning with the last digit. | |
| Oct 15, 2014 at 19:43 | comment | added | Ali | @Otaia Thanks for checking it. :) Will have to check some more (prime?) numbers out... | |
| Oct 15, 2014 at 19:39 | comment | added | SQB | It shouldn't end in 890625, it should start with 526098. | |
| Oct 15, 2014 at 19:33 | comment | added | Otaia | I applied the technique described here: 890625^890625 does indeed end in 890625. There are other numbers that have powers whose last digits are their roots, though ... see the powers of 7. There may be a larger number. Also, there aren't any 6s in that box, are there? Although Ernie did pull a 6 out of thin air. | |
