Equation with exponents. Not solved yet. Please help

Hi!

I was wandering if anyone of you could help me solve the following equation:

where are integers.

I know the best way to solve it is to use modulo but, to be honest, I don't really know how modulo works in such equations.

Maybe you have another approach to this task - please share it :)

Re: Equation with exponents

Here's 2:

(2,1,3): 2^2 + 5^1 = 3^2

(3,0,3): 2^3 + 5^0 = 3^2

Probably loads more...

Perhaps someone else will have a "trick" for you...

Thanks:)

I do hope someone will have a trick for me, because there needs to be a proof that there aren't any more solutions.

Well, I wrote short program to find these: contrary to what

I had asssumed, couldn't find any!

Why do you think there's more, islam? Got an example?

By the way, for your benefit, I suggest you start using

are (not r) and you (not u): may cause problems if you're

typing a math problem with variables.
