Let R and S be two equivalence relations on a set A Then : A. `R uu S` is an equvalence relation on A B. `R nn S` is an equirvalenee relation on A C. `R - S` is an equivalence relation on A D. None of these

Let R and S be two equivalence relations on a set A Then : " " A. R uu S is an equvalence relation on A " " B. R nn S is an equirvalence relation on A " " C. R - S is an equivalence relation on A " " D. None of these

If R and S are two equivalence relations on a set A then R nn S is also an equivalence relation on R.

Let R_1 and R_2 be two equivalence relations in the set A. Then:

Let R and S be two non - void relations on a set A.

If R and S are two equivalence relation on the set then prove that RcapS is also an equivlaence relation on the set.

If R_1 and R_2 are equivalence relations in a set A, show that R_1 nn R_2 is also an equivalence relation.

If R_1 and R_2 are equivalence relations in a set A, show that R_1 nn R_2 is also an equivalence relation

If R_1 and R_2 ·are equivalence relations in a set A, show that R_1 nn R_2 is also an equivalence relation.

If R_1 and R_2 are equivalence relations in a set A, show that R_(1) cap R_2 is also an equivalence relation.
