Hi, at the beginnig I want to apologise for any language mistateks i make - i'm polish
I have serious problem with such task: Solve equation x4-y3-4=0 in odds. I took it from an online maths competition.
I tried replacing both x4 and y3 with (2n-1)4 and (2m-1)3 by it didn't help me anyway.
It's also possible that this equation has no solution, in this case how to prove it?
Thanks a lot for your time
