The Last Theorem

Fermat's Last Theorem states that there are no three positive whole numbers, a, b, and c, that can satisfy the equation aⁿ + bⁿ = cⁿ when n is an integer greater than 2. In other words, unlike the familiar Pythagorean theorem (which works for n=2), for higher powers (like cubes or fourth powers), you cannot find whole-number solutions that make the equation true. This theorem was conjectured in the 17th century by Pierre de Fermat and was proven mathematically by Andrew Wiles in 1994.
