Let $m$ be a fixed positive integer that is the product of distinct prime factors of the form $(3k+2)$, such as $5 times 11$.



Prove that there exist infinitely many primes $p$ such that $3^{3p-2}equiv 1 pmod m$?



I started with assuming that there exists finitely many primes satisfying such equation. How to contradict this statement? May be we can create one more prime satisfying given equation? I am stucked. Please help
