Problem 1126

Write true or false for the statement.

{m ,n, j, k} = {j, k, n, m}




Look at sets {m , n, j, k} and {j, k, n, m}. They have the same number of element, four.

The element are exactly the same, though not necessarily in the same order.

Therefore the set are equal.

{m, n, j, k} = {j, k n , m}
