Need a Conversation Topic Tonight?

Shock, horror, I've actually been doing some Maths recently.

So here's one for you to discuss with the family over dinner tonight.
This is taken from Number Theory Example Sheet 4.

Given that 2 is a primitive root of 5, find a primitive root b of 25 (b is of the form 2+5x). Is this same b a primitive root of 125?

Nope, I've not done it yet either...
