ii) It can't be perfect square because the ending of 5963 is 3. (Same property as the first one).

iii) Same as 1st and 2nd property as it ends with 7,so it can't be perfect square.

iv) It ends with digit 8.So, it isn't a perfect square.

v) As it ends in one zero, so it isn't a perfect square. (one of the properties of perfect squares that a number ending in an odd numbers of zeros is never a perfect square.

vi) again same as 5th that it ends with odd number of 0.

vii) Again 2500000 have 5 zeros at last which is odd. So, it isn't a perfect square.
