I was just working on some problems from a text book I own (for fun).(adsbygoogle = window.adsbygoogle || []).push({});

I am not sure how to start this problem at all.

Here's the question: Show that 3 is a quadratic non-residue of all Mersenne primes greater than 3.

I honestly don't know how to start. If I could get some help to push me in the right direction that would be great.

Thanks
