Let `R_1` and `R_2` be equivalence relations on a set A, then `R_1uuR_2` may or may not be

Let R_(1) and R_(2) be equivalence relations on a set A, then R_(1)uu R_(2) may or may not be

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

If R is an equivalence relation on a set A, then R^-1 is

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.

If R_1 and R_2 are equivalence relations in a set A, show that R_1nnR_2 is also an equivalence relation.

If R_1 and R_2 are equivalence relations in a set A, show that R_1nnR_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.
