Hi,
Could anyone please help me with this homework problem:
prove that there exists no solutions for:
X^n + Y^n = Z^n where n > 2
soon please coz I need to hand this in next week.

You silly person you. I don''t have 300 years to try and prove that.

I think some guy did end up proving it, but they never told exactly what the solution was.

Euler is credited with proving X^n + Y^n != Z^n where n > 2
for n=3 and subsequent cases for specific values of n have been proven by other mathematicians throughout history.
However, it was proven for all cases of n>2 by Andrew Wiles (in 1994 I think, could be wrong as this is from memory) by proving the the ShimuraTaniyamaWeil conjecture.
Just a irrelevent (but highly interesting) piece of information for any budding mathematicians...

There are however solutions to x^n + y^n + z^n = c^n for n=3 and n=4. Maybe this is what you meant?

Andrew Wiles, a Cambridge mmathematician, showed that x^n + y^n != z^n for all n > 2.
Elliptical equations and modular forms are understood by few mathematicians anyway. Good luck!

Next time I'll actually read what I write before posting.
Whilst programming, I've found "!=" and "==" are a common cause of quite a few logical errors.
Apologies to python_regious for misreading your post as well.

I knew this but unfortunately it wasn't what I meant. It was just a stupid mistake unfortunately, and not a misunderstood post by me.
