Step-by-step explanation:
first we need to know the squares of numbers up to 25 so that this type of problems can be easy to solve
Given 564
23^2 = 529
24^2 = 576
23^2 < 564 < 24^2
If the question asked least number to be subtracted we must check with lesser number I.e 23^2 = 529
Here the question asked about the least number to be added so we must check with larger number I.e 24^2 = 576
Hence least number to be added = 576 - 564 = 12
Therefore the least number to be added to 564 to make it a perfect square is 12.
