To Find:

Which of the following is a perfect square?

Solution :

• No square numbers end with 2, 3, 7, or 8.

• The perfect Square number ends with 0, 1, 4, 5, 6, and 9.

• The number of zeros at the end of a square number is always even.

• A number ending with an odd number of zeros is never a perfect square.

1) The square root of 1057 = √1057 = 32.51

2) The square root of 7928 = √7928 = 89.03

3) The square root of 625 = √625 = 25

Hence, 625 is the perfect square of 25.
