This c++ program demonstrates the implementation of fermat’s little theorem for the modular multiplicative inverse to exist, the number and modular must be coprime.

Fermat's little theorem states that if p is a prime number, then for any integer a, the number a p − a is an integer multiple of pin the notation of modular arithmetic, this is expressed as. Introduction fermat’s last theorem fermat’s last theorem states that the equation x n+yn= z , xyz6= 0 has no integer solutions when nis greater than or equal to 3. I have managed to show that $(a + b)^p \equiv a^p + b^p \pmod p$, $a$ and $b$ being any integer and $p$ any prime how can i prove from this that \$a^p \equiv a \pmod p.
