Pritesh, I sent an e-mail with some further questions, as the formatting in the comments section would make it unreadable.

J.R. I believe that 4 is correct. It translates to 50/8, which is 6.25 in base 10. In base 4, that equals 12.1, as the number behind the decimal is 1/4. However, I think #3 should be '41^0.3=5', since (presumably) you're trying to take the square root of 41. In base 6, 0.5 is 5/6, and 25^(5/6) is not a rational number in any base. Please correct me if I'm wrong on this, as it's been a while since I've dealt with base 6 decimals. :-)

As a heads up, http://oeis.org/A138591 counts 1 as a polite number, but the test suite does not.
