Okay, do that.
Fermat's Last Theorem states that no three positive integers a, b, and c can satisfy the equation an + bn = cn for any integer value of n greater than two.
Proof? And it's not an, but \(a^n\).
the general proof for all n required only that the theorem be established for all odd prime exponents.[49] In other words, it was necessary to prove only that the equation an + bn = cn has no integer solutions (a, b, c) when n is an odd prime number. This follows because a solution (a, b, c) for a given n is equivalent to a solution for all the factors of n. For illustration, let n be factored into d and e, n = de. The general equation an + bn = cn implies that (ad, bd, cd) is a solution for the exponent e (ad)e + (bd)e = (cd)e. Thus, to prove that Fermat's equation has no solutions for n > 2, it suffices to prove that it has no solutions for at least one prime factor of every n. All integers n > 2 contain a factor of 4, or an odd prime number, or both. Therefore, Fermat's Last Theorem can be proven for all n if it can be proven for n = 4 and for all odd primes (the only even prime number is the number 2) p.
It's not an + bn = cn, but it is \(a^n + b^n = c^n\).
