Of course! I´d look into it...

Not exactly. Its possible to compute square of 2 (269916694664582966990754893514409**2 + 108309988975954046249057727301124**2) , but why it´s not possible to compute higher (such as 4)? It works for 2, so it must also work with 4.

thanks, but this isn´t exactly I´m looking for. I mean this:

546516546654461986448

how can I quickly compute which power gives me 5XXXXXXXXXXXXXXXXXXXX? X-random value, but that doesn´t matter - I want to give the length.

Yes, I am programmer (not a good one). I already found what I was looked for.

Thanks for clarification.

Aha, integer factorization.

So 1676962425600 is 2^8 * 3^2 * 5^2 * 7 * 11^2 * 37 * 929

>If they were all prime  and you were told how many there were then you could

so I have 2,3,5,7,11,37,929. How can I determine correct exponents?

Thanks.
