**Let π = {π, π, π} and π
= {(π, π), (π, π), (π, π), (π, π), (π, π)}, find [π], [π] and [π] (that is the equivalent class of a, b, and c). Hence or otherwise find the set of equivalent class of π, π and π?**

**Here's the Solution to this Question**

LetΒ $π = \{π, π, π\}$Β andΒ $π
= \{(π, π), (π, π), (π, π), (π, π), (π, π)\}$. Taking into account thatΒ $[x]=\{y\in S:(y,x)\in R\}$, we conclude that Β $[π]=\{a\},\ [b]=\{b,c\},\ [c]=\{ c, b\}=[b].$Β The set of equivalent classes isΒ $\{[a],[b]\}.$
