We can find the sq. number by prime factorisation and estimation method
to find it by estimation method break given number in the set of 2.
e.g. 6_76
in the first set (76) in the unit's place there is 6 which comes in the square of 6.
therefore in units place there will be 6.
in second set there is only 6 so we have to find nearest perfect square to it which is 4, that is the square of 2.
therefore the second number is 2.
the required number is 26.
