Label each of the following statements as either true or false.

Let R be an equivalence relation on a nonempty set A and let a and b be in A . If b ∈ [ a ] , then [ b ] = [ a ] .

To determine

Whether the statement, “If R is an equivalence relation on the nonempty set A and let a and b be in A. if b∈[a] then [b]=[a] ” is true or false.

Explanation

Consider the statement, “If R is an equivalence relation on the nonempty set A and let a and b be in A. if b∈[a] then [b]=[a] ”

Let R be an equivalence relation on nonempty set A. For each a∈A, the set [a]={x∈A|xRa} is called equivalence class containing a.

Given that b∈[a].

By using definition of equivalence class,

⇒bRa ………… (1)

Let x∈[a]

By using definition of equivalence class,

⇒xRa

From (1),

⇒bRa

By using R is symmetric,

⇒aRb

Thus xRa and aRb
