A prime number is an integer greater than 1 that is evenly divisible by only 1 and itself. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided by 1, 2, 3, and 6.Write a Boolean function named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, and false otherwise. Demonstrate...

Prove by induction that their direct product Ck1×Ck2×....×Ckn is cyclic if and only if the ki's are pairwise coprime which means gcd(ki,kj)=1 for every i not equals j in {1,...n}.

Let a,b be any relatively prime positive numbers. (The case b = 1 is allowed). We have the rational number a/b. Without appealing to anything but Euclid’s lemma (no use of ε(p, m)) show that if p is prime then p does not equal (a/b)^2. That is √p is irrational. Hint: if p = (a/b)^2 then we have p(b^2) = a^2. Derive p|b and then show p|a which is a contradiction.
