Question

Let R = {(a, b): a = a²} for all, a, b ∈ N, then R salifies.

Options

• Reflexitivity

• Symmetry

• Transitivity

• None of these

Answer 1

None of these

Explanation:

(i) 2 ≠ 2² ⇒ 2 is not related to 2.

(ii) 4 = 2² ⇒ 4 R². But 2 ≠ 4², so 2 is not related to 4.

(iii) 16 R 4, 4 R², But 16 is not related to 2.
