Question
If A = {1, 2, 4}, B = {2, 4, 5} and C = {2, 5}, write (A - C) × (B - C).
✓

Answer

We have, A = {1, 2, 4}, B = {2, 4, 5} and C = {2, 5} $\therefore$ A - C = {1, 2, 4} - {2, 5} A - C = {1, 4} and, B - C = {2, 4, 5} - {2, 5} B - C = {4} Now, (A - C) × (B - C) = {1, 4} × {4} (A - C) × (B - C) = {(1, 4), (4, 4)}
