A perfect square is the result of a number being multiplied by itself. For instance, 9 is a square number as it is the result of 3x3. If a number is a square, its factors can all be paired up. In the case of 24, its prime factors are 2, 2, 2 and 3. While two of the 2s can pair up, there is another 2 and a 3 left over. Thus, we can say for certain that 24 is not a square.

Perfect squares cannot have digits after the decimal point.
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.
