0 Guest Posted June 11, 2011 Report Share Posted June 11, 2011 (edited) My first thought is maybe it is the factors. 3435 = 15*229. This can be written as 15*(152-22) 5141 = 53*97. This can be written as (50+3)*(50*2-3) 6174 = 2*32*73 Edited June 11, 2011 by Nana7 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted June 11, 2011 Report Share Posted June 11, 2011 oops, sign was off below, correction for 15*229. This can be written as 15*(152+22) My first thought is maybe it is the factors. 3435 = 15*229. This can be written as 15*(152-22) 5141 = 53*97.

0 Guest Posted June 11, 2011 Report Share Posted June 11, 2011 you've got the right idea for number 1. number 2 and 3 are way off! Quote Link to comment Share on other sites More sharing options...
0 Guest Posted June 11, 2011 Report Share Posted June 11, 2011 1. Exponents are the key here... 2. The answer might not be base-10... 3. It might take a few steps (at most 7) to get to this. But how? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted June 12, 2011 Report Share Posted June 12, 2011 5141 = (8B)^2 in pentadecimal numbers (base 15) Quote Link to comment Share on other sites More sharing options...
0 Guest Posted June 14, 2011 Report Share Posted June 14, 2011 5141 = (8B)^2 in pentadecimal numbers (base 15) close, the answer I'm looking for is not pentadecimal... 5141 is base 10, the answer I'm looking for not. 5141 (base 10) = XXXX (base XX) there's something unique about it (found out it's a property shared by 3 other numbers) Quote Link to comment Share on other sites More sharing options...

Cool. Of course it's also true for all one-digit numbers Quote Link to comment Share on other sites More sharing options...
