Primitive root of prime number

WebMar 6, 2024 · m= 8. Our next goal is to show that each prime number has a primitive root (see Theorem 10.6). The proof requires three lemmas and the existence of a primitive root of a prime is given, though a technique of finding the primitive root is not part of the proof. Dudley comments (see page 77): “For these reasons, you do not Weba = b2 mod p for a prime p. In that case we say that a has a square root mod p. Recall that x is a primitive root of Z∗ p if the smallest integer i so that xi = 1 mod p is p − 1. This means that every number u 6 = 0 mod p can be uniquely posed as u = xj mod p. We know that Z∗ p has many primitive roots. I would recommends using that in ...
