They are: 4*4 = 16
They are: 49+16 = 65

16 can have only one square and that is 256.
The two square numbers that, when one is subtracted from the other, equal seven are 16 and 9. This is because (4^2 - 3^2 = 16 - 9 = 7). Thus, the square numbers are 16 (from (4^2)) and 9 (from (3^2)).
The two square numbers that have a difference of 9 are 25 and 16. This can be expressed as (5^2 = 25) and (4^2 = 16). The difference between them is (25 - 16 = 9).
They can be: 16 -4 = 12
They are: 49+16 = 65

16 and 9
The two square numbers that have a difference of 9 are 25 and 16. This can be expressed as (5^2 = 25) and (4^2 = 16). The difference between them is (25 - 16 = 9).
52 - 32 = 16.
25 - 9 = 16

The pair of square numbers that add up to 80 is 16 and 64. Specifically, (4^2 = 16) and (8^2 = 64), since (16 + 64 = 80).
These are square numbers. 1, 4, 9, 16, 25 1 2, 2 2, 3 2, 4 2, 5 2, next number is 6 2 = 36
