Let N be the set of all natural numbers and R be a relation on N x N defined by (a, b) R (c, d) ⇔ ad = bc for all (a, b), (c, d) ∊ N x N. Show that R is an equivalence relation on N x N, Also, find the equivalence class of (2, 6), i.e., [(2, 6)].Read more on Sarthaks.com - https://www.sarthaks.com/3491875/let-n-be-the-set-of-all-natural-numbers-and-be-relation-on-x-n-defined-by-a-b-r-c-d-ad-bc-for-all-a
