Select the symbol = (equal to) or ≠ (not equal to) to make the expression true.

{2, 4, 6} ? {6, 4, 2}

The symbol would be '='

Step-by-step explanation:

Two sets are called equal if they contains same elements in them ( however in any order ),

Here, the given sets,

{2, 4, 6}

{6, 4, 2}

Since, both sets having the elements 2, 4 and 6,

Hence, we can say that,

Sets {2, 4, 6} and {6, 4, 2} are equal sets,

Or {2, 4, 6} = {6, 4, 2}
