From the sets given below, select equal sets:
A = {2, 4, 8, 12},    B = {1, 2, 3, 4},   C = {4, 8, 12, 14}, 
D = {3, 1, 4, 2},    E = {- 1, 1},   F = {0, a},
G = {1, - 1},   H = {0, 1}

Solution:

The given sets are as follows:

A = {2, 4, 8, 12}, B = {1, 2, 3, 4}, C = {4, 8, 12, 14} D = {3, 1, 4, 2}

E = {- 1, 1}, F = {0, a}, G = {1, - 1}, H = {0, 1}

We can see that the elements of B and D are equal though the order is different.

So B = D.

In the same way, we can say that E = G.

We cannot find any other two sets which are equal from the given list.

Hence the equal sets are, B = D and E = G

From the sets given below, select equal sets: A = {2, 4, 8, 12}, B = {1, 2, 3, 4}, C = {4, 8, 12, 14} D = {3, 1, 4, 2} E = {- 1, 1}, F = {0, a}, G = {1, - 1}, H = {0, 1}

Summary:

We are asked to select equal sets from the sets given below. A = {2, 4, 8, 12}, B = {1, 2, 3, 4}, C = {4, 8, 12, 14} D = {3, 1, 4, 2} E = {- 1, 1}, F = {0, a}, G = {1, - 1}, H = {0, 1}. We have found that B = D and E = G
