solving congruence $a^{6p−6} equiv 1 pmod{9p}$
$begingroup$
Let $p$ be a positive prime number different from $3$ and $a$ be an integer not divisible neither by $3$ nor by $p$. Show that in this case $a^{6p−6} equiv 1 pmod{9p}$

I have no idea about solving an equation. I need an example. If I know the first solution, I can do it in a similar way.

Apply Euler's theorem, since $varphi(9p)=varphi(9)cdot varphi(p)$

I don't know what's the next steps. I get φ(9p)= 6⋅φ(p).
