Answer:
We can find the sq number by prime factorization 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 units 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.
