Answer»

(i) We know that,

Any number which ends with an odd number of zeros is not a perfect square

Also, the given number 360 is ending with the digit 0

Therefore,

The given number is not a perfect square

(ii) We know that,

Any number which ends with an odd number of zeros is not a perfect square

Also, the given number 6400 is ending with the digit 0

Therefore,

The given number is not a perfect square

(iii) We know that,

Any number which ends with an odd number of zeros is not a perfect square

Also, the given number 2500000 is ending with the digit 0

Therefore,

The given number is not a perfect square
