Re: positive integers

(3,1) and (5,3) are two, and there aren't any others for x<250 so I'd guess they're the only two.
Not sure how to prove that though.


Why did the vector cross the road?
It wanted to be normal.

Re: positive integers

Hi Tony;

  I also only found (3,1) and (5,3) and I searched up until 3^3211 + 5. Have no proof yet that these are the only ones.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
