If A = 1, 2 , from the set A × A × A. - Vidyadip

Question

If A = {1, 2}, from the set A × A × A.

✓

Answer

We have, A = {1, 2 } $\therefore$ A × A = {1, 2} × {1, 2} = {(1, 1), (1, 2), (2, 1), (2, 2)} $\therefore$ A × A × A = {1, 2} × {(1, 1), (1, 2), (2, 1), (2, 2)} = {(1, 1, 1), (1, 1, 2), (1, 2, 1), (1, 2, 2), (2, 1, 1), (2, 1, 2), (2, 2, 1), (2, 2, 2)}
