Answer 1

Answer:

When something is known about Zn, it is frequently fruitful to ask whether something comparable applies to Un. Here we look at Un in the context of the previous section. To aid the investigation, we introduce a new quantity, the Euler phi function, written ϕ(n), for positive integers n.

Definition 3.8.1 ϕ(n) is the number of non-negative integers less than n that are relatively prime to n. In other words, if n>1 then ϕ(n) is the number of elements in Un, and ϕ(1)=1.

Example 3.8.2 You can verify readily that ϕ(2)=1, ϕ(4)=2, ϕ(12)=4 and ϕ(15)=8.

Example 3.8.3 If p is a prime, then ϕ(p)=p−1, because 1, 2, …, p−1 are all relatively prime to p, and 0 is not.

For any number n, ϕ(n) turns out to have a remarkably simple form; that is, there is a simple formula that gives the value of ϕ(n). We've already seen how simple it is for primes. As is typical of many results in number theory, we will work our
