WebReflexivity - As every integer is equal to itself, that is, a = a for all a ∈ Z, it satisfies a ≥ a for all a ∈ Z. This implies (a, a) ∈ R for all a ∈ Z. Hence, R is reflexive. Symmetricity - For a, b ∈ Z, let (a, b) ∈ R ⇒ a ≥ b. This does not imply that b ≥ a. For example, 12 ≥ 9 but 9 is not greater than or equal to 12.

WebJan 9, 2024 · For the relation to be reflexive then x + x, would need to be a power of 3, but x + x = 2 x, which is an even number and so it can't be a power of 3, and so x R x doesn't hold, which means the relation is anti-reflexive. All of this is rather simple to work out in my head, but how would I prove it mathematically?
