Sorted by: 4. It's exactly the same as proving 2 is irrational. Suppose 5 = ( a b) 3 where a, b are integers and g c d ( a, b) = 1) [i.e. the fraction is in lowest terms]. The 5 b 3 = a 3 so 5 divides a 3 but as 5 is prime (indivisible) it follows 5 divides a. So a = 5 a ′ for some integer a ′. So 5 b 3 = ( 5 a ′) 3 = 125 a ...
