May I suggest
[for no particular reason... muauahahaha]
As for this specific problem... use a square/multiply method
e.g. a^7 == (((a^2)*a)^2)*a
If you're not into coding [and why not!?!?!] I'd suggest an elcheapo dover
series text on number theory. They cost like 10$ and will explain all of
the relevent theory quite well.
