Whose last theorem states that there are no instances possible for positive integers X, Y, Z and n so that Xn + Yn = Zn where n is greater than two? The little n's are meant to be above the capital X, Y and Z as in square roots.

that would be the fermat's last theorem. supposedly he had been going through a book proving theorems in the margins. when he got this, he stated that he had a remarkable proof for this,but did not have space in the margin to prove it. this has baffled mathematicians for hundreds of years until i believe sometime in the 1990s, Andrew Wiles of Princeton University proved the theorem. However, it was not the same proof Fermat was probably thinking of, considering that a branch of mathematics was invented to prove this. the proof was over 200 pages, definitely a 20th century proof.
