Fermat's Last Theorem

Definition

Fermat's Last Theorem states that there are no three positive integers $a$, $b$, and $c$ that satisfy the equation $a^n + b^n = c^n$ for any integer value of $n$ greater than 2. This theorem, proposed by Pierre de Fermat in 1637, was famously unproven for over 350 years until Andrew Wiles finally demonstrated its truth in 1994, connecting various fields of mathematics and showcasing the depth and complexity of number theory.
