Hi I'm Ryan Ault. I'm a physicist and this is how to solve for primitive roots. The first thing we should do is examine our prime number. We can call our prime number P and after we identify our prime number we can look at an equation, 2 to the N mod P. In this example we've chosen 2 as our primitive root so we are checking to see if 2 is a primitive root of the prime number P and what we have to do is look at this equation, 4, N is equal to 1 to N equal to 2 minus 1. Once we iterate through all these possible values we look to see if the outcome is unique and between 1 and P minus 1. As an example we can choose a prime number with P being equal to 3 and we can search for primitive roots of 2. So we find that 2 to the 1 mod 3 is equal to 2 and 2 to the 2 mod 3 is simply equal to 1. So we find that each outcome is unique and it's in the range from 1 to 2 so we find that 2 is a primitive root of 3. I'm Ryan Ault and this is how to solve for primitive roots.
