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 625 = √625 = 25
3) The square root of 7928 = √7928 = 89.03
4) The square root of 64000 = √64000 = 252.98
Hence, 625 is the perfect square.
