On n − {1}, the relation r given by a r b iff the prime factorizations of a and b have the same number of 2's. for example, 48 r 80 because 48 = 24 · 3 and 80 = 24 · 5. name three elements in each of these classes: 7, 10, 72.

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:
