The idea is to solve certain problems, many of which appear in real life, and which don't have whole-number solutions.
No. 2.25 is not a perfect square but it is rational.
All positive integers which are not perfect squares.
No. 1.5^2 = 2.25 is rational.
683 perfect squares.
Perfect squares cannot have digits after the decimal point.
To find the perfect squares between 20 and 150, we need to determine the perfect squares less than 20 and the perfect squares greater than 150. The perfect squares less than 20 are 1, 4, 9, and 16. The perfect squares greater than 150 are 169 and 196. Therefore, there are 5 perfect squares between 20 and 150: 25, 36, 49, 64, and 81.
There is no pair of perfect squares that sums to 21. And the question is pointless if it is not about perfect squares because in that case there are infinitely many answers.There is no pair of perfect squares that sums to 21.

45 is not a perfect square number. the closest perfect squares are 49 and 36. But it is the square of the irrational number 6.708204... (an infinite, non-terminating, non-repeating decimal).
81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.
No. Convention defines perfect squares as squares of positive integers.
By definition, ALL perfect squares are whole numbers!
Natural numbers which are the scales of some natural numbers are perfect squares
