Webdivisor of a and b and hence gcd(a;b) 5. This contradicts our assumption that gcd(a;b) = 1. Therefore 5 p 5 is irrational. (d) If p is a prime, then p p is irrational. Solution: Suppose that p p is rational. Then p p = a=b where a;b 2Z. We may always cancel common divisors in a fraction, hence we may assume that gcd(a;b) = 1. Squaring both ...
