2. (a) In lecture, we saw Euler’s Totient Function Φ(n), which is defined as the number of positive integers less than or equal to n that are relatively prime to n. Suppose I want to compute Φ(84), as per lecture. I know that 84 = 14 × 6, so I compute Φ(14) and multiply it by Φ(6). Do I get the right result? Briefly, why does this work or not work? Your answer should be brief, but not as simple...
oblemns for Solution: 1. Recall that Euler's phi function (or called Euler's totient function) φ(n) is defined as the number of integers m in the range 1< m<n such that m and n are relatively prime, i.e., gcd(rn, n) l. Find a formula for φ(n), n 2. (Hint: Factor n as the product of prime powers. i.e., n-TiỀ, where pi's are distinct primes and ei 〉 1, i, where p;'s are distinct primes and e > 1 t. oblemns for...

Exercise 2. Let φ denote the Euler totient function. (i) Prove that for all positive integers m and n, if m,n are relatively prime (coprime), then φ(mn-o(m)o(n) (ii) Is the converse true? Prove or provide a counter-example.
Part 15A and 15B (15) Let n E Z+,and let d be a positive divisor of n. Theorem 23.7 tells us that Zn contains exactly one subgroup of order d, but not how many elements Z has of order d. We will determine that number in this exercise. (a) Determine the number of elements in Z12 of each order d. Fill in the table below to compare your answers to the number of integers between 1 and d that are...
(3.5) Summing the Euler S-function (n): The Euler 6-function 6(n) counts the number of positive integers less than or equal to n, which are relatively prime with n. Evaluate 4(d), and prove that your answer is correct. (3.4) Relatively Prime Numbers and the Chinese Re- mainder Theorem: Give an example of three positive integers m, n, and r, and three integers a, b, and c such that the GCD of m, n, and r is 1, but there is no...
Show that if n is a positive integer and a and b are integers relatively prime to 1 such that (On(a), On(b))1, then Show that if n is a positive integer and a and b are integers relatively prime to 1 such that (On(a), On(b))1, then
Use the Euler-Totient Function formula to find all values n, such that phi(n)<=5. Prove that the list is indeed correct.
