    Step-by-step explanation:

    Prime factorize the given number. All factors should have pair. If all factors have pair, then it is a perfect square

    EG: 36 : Factors of 36 are 2,3,2,3. Here there are two 2's and two 3's. so 36 is a perfect square.

    EG: 24: Factors of 12 are 2,2,3. Here 3 is without pair. so it is not a perfect square.
