Little explorations with HP calculators (no Prime)

find a, b, c, n such that

a^n + b^n = c^n

It's trivial to find solutions to this, but if you add these conditions:

a, b, c, n ∈ N
a, b, c > 0
n > 2

It's suddenly a lot harder. :-)

That's not hard, I could write down my marvelous little proof but this text box is too narrow.
