The two square numbers with a difference of 21 are 25 and 4. This is because (5^2 = 25) and (2^2 = 4), and their difference is (25 - 4 = 21).
None, although "perfect square" tends to be used for whole numbers.
Well, darling, the square numbers that have a difference of 12 are 16 and 4. You see, 16 minus 4 equals 12. It's as simple as that, sugar.
