Fermat’s last margin note. | Lapham’s Quarterly
www.laphamsquarterly.org › miscellany › fermats-lastAfter his death in 1665, Pierre de Fermat’s son Clement-Samuel discovered a copy of Arithmetic, a third-century math book by Diophantus, in which Fermat had written on one page, “It is impossible…for any number which is a power greater than the second to be written as the sum of two like powers [x n + y n = z n for n > 2]. I have a truly marvelous demonstration of this proposition which this margin is too narrow to contain.”

While there are infinitely many cases where this equation is true when n = 2 (called the Pythagorean triples ), the Last Theorem says that there is no solution if n is greater than 2. The problem was to solve the theorem, either by proving it or by producing a counterexample.
Fermat's Last Theorem - Wikipedia
https://en.wikipedia.org/wiki/Fermat's_Last_TheoremIn ancient times it was known that a triangle whose sides were in the ratio 3:4:5 would have a right angle as one of its angles. This was used in construction and later in early geometry. It was also known to be one example of a general rule that any triangle where the length of two sides, each squaredand then added together (3 + 4 = 9 + 16 = 25), equals the square of the length of the third side (…
