Can u prove this simple but very important fact?

suppose c is even.  then this means that a is even and b is even, or a is odd and b is odd.  that is, a and b have the same parity.  we could not have a even, b even and c even because otherwise, a, b and c would not be coprime.  so a is odd and b is odd, if c is even.  I am unable to do this right now (I have forgotten my math, sorry), but I believe you could dispense with a proof which, loosely speaking, allows you to conclude that c must be odd on the basis of the fact that c^n = 0 (mod 2) is too restrictive (i.e. not all nth powers are even (except for those containing 2^n as a factor), or in other words, most nth powers are odd).  sorry, am not much help.\n\nincidentally though (if I may mention it here), a proof for FLT has already been published (and verified) in 1994.  the original proof comprised a whole edition of the Annals of Mathematics for that year and is composed of two papers, to wit: \n\nModular Elliptic Curves and Fermat's Last Theorem\n\nAND\n\n(again, it is easy to forget article titles, so please just search on the WWW web for it... :-))\n\nthe proof is subtle and surprisingly involved, and there is actually a page on the Internet dedicated to presenting the mathematics behind the proof to the general mathematical audience.  try googling "The Mathematics of Fermat's Last Theorem".\n\nhappy reading!

it is not true\nbut i have no proof

When there is proof!!

Sounds like a Math/Science type question to me. Why are you posting it here?\n\nBesides, I have the the slightest idea.

can u a little explain?

No, nobody really can prove it, with assuming several axioms\nfirst. There are certain things you have to assume are true in your universe, without necessary being able to check them. From those axioms, you can derive conclusions (theorems) that are always true, but only in that particular\nuniverse. The discussed operation of addition is one such theorem. If you assume that the axioms of natural numbers are true, then this addition becomes quite trivival. If you assume those axioms of natural numbers to be false, then the above operation of addition might become false with a different set of supposition. In other words, only with the facts given, one cannot prove, nor disprove, the fact of addition. It all depends on the set of assumptions you would have made before adding the two ones.

Dont the proof have to be in the pudding an U know it do.

is this discovery has any proof? if it is having . You have to write a research paper for it. then you can send it to any international journal of repute such as IEEE Journals(http://ieee.org)

I see. You just want to prove something.

there is a very simple formula to do this

OF COURSE!!! obvious isn't it???

Anybody have any proof....one way or the other?

Can u make ur question clearly \nthx ,

i'll keep it very simple, the answer really is 2

yes it is true.... u will believe it soon

It's possible. We don't know it and probably can't prove it anytime soon. Go see my answer to these questions, as it is very similar to your question. (they're rather long)\n\nPS Penguins!!!

I think your question is proof enough.
