Fermat's Last Theorem
In number theory, Fermat's Last Theorem(sometimes calledFermat's conjecture, especially in older texts) states that no three positiveintegers a, b, and c satisfy the equation a^n^+b^n^=c^n^ for any integer value of n greater than 2. The cases n = 1 and n = 2 have been known to have infinitely many solutions since antiquity.
