FERMATS LAST THEOREM

Log in to reply

I'm pretty sure Fermat's Last Theorem

Log in to reply

Fermat's Little Theorem can be proved using induction.

Can u prove it by induction plz show?

Log in to reply

It's not by induction, but an easy proof of Fermat's little theorem would be that \(x^p \equiv (1+1+1+...+1)^p \equiv (1^p+1^p+...+1^p) \equiv x \pmod p \) with \(x\) times number \(1\). This is possible because in Pascal's triangle on prime rows the numbers are multiples of p except for the first and last terms which are \(1\). This can be easily proven by using binomial formula.

I can give you a proof .

Okay get your calculators and try this:

\(\sqrt[12]{1782^{12}+1841^{12}}\)

\(=1922\) right?

So this implies that \({1782^{12}+1841^{12}=1922^{12}}\)

Does this disprove Fermat's Last Theorem?

Of course not!

The calculator is wrong.

BTW: A quick check to see that \(1782^{12}+1841^{12} \neq 1922^{12}\) is to note that the left side is odd whereas the right side is even.

Took some time to realize... The actual answer is \(1921.99999995586722540291132837029507293441170657370868230...\) Unfortunately, most calculators round the answer.

If I remember correctly, that "equation" was from a Homer Simpson episode.
