WebRaji 5.2, Primitive roots for primes: 8. Let r be a primitive root of p with p 1 (mod4). Show that r is also a primitive root. I suppose p is a prime. Indeed, 2 is a primitive root modulo 9, but 2 is not. Write p = 4m+1. As r is a primitive root, the numbers r;r2;r3;:::;r4m are a complete set of nonzero residues modulo p. Note that r2m 6= 1 ... WebFor a to be a primitive root modulo 17, the powers of a should yield every (nonzero) value mod 17. This is equivalent to saying that the order of a mod 17 is 16. That is, a is a …

WebAnswer (1 of 2): I just answered a question about Euler’s Totient Function \phi(n); this is related. A primitive root of a number n is a number g whose powers generate all numbers relatively prime to n, modulo n. For n=18, we’re working modulo 18, meaning we’re only worrying about the remainder... Web11 2 = 10, and thus 2 is a primitive root modulo 11. This tells us that 11 has ˚(˚(11)) = ˚(10) = 4 incongruent primitive roots. In particular, these roots are 2;23 = 8;27 = 128 7;29 = 512 6. Thus f2;6;7;8gis a complete set of incongruent primitive roots modulo 11. This result does have one weakness: it tells us what happens if there are any ... WebA unit g ∈ Z n ∗ is called a generator or primitive root of Z n ∗ if for every a ∈ Z n ∗ we have g k = a for some integer k. In other words, if we start with g, and keep multiplying by g … paint like a child 秦基博
