Fermat’s Last Theorem, one of the most famous theorems in the history of mathematics, states that:

It is impossible to separate any power higher than the second into two like powers,

or, more formally:

If an integer n is greater than 2, then aⁿ + bⁿ = cⁿ has no solutions in non-zero integers a, b, and c.

With its published proof, this ‘theorem’ is sometimes called the Fermat–Wiles Theorem.

The theorem was proved by Sir Andrew Wiles for which he received the Nobel Prize! :O
