remainder of the division $2^{1990}/1990$ How do we find the remainder of the division $2^{1990}/1990$?
I actually tried it through Fermat's theorem but couldn't arrive at the answer directly.
Well, since 1990 is not prime, you might want to look into Euler's Theorem, which extends Fermat's Little Theorem.
