No. Square numbers are from numbers being squared like 2 squared is 4. Squaring a number is multiplying it by itself so 3x3=9, 4x4=16, 5x5=25, and so on. The closest square numbers to 40 are 36 (6x6) and 49 (7x7) there are no whole numbers to square in between 6 and 7 so 40 cannot be a square number

In that case, the answer is as follows: There is no number such that it is a perfect sqiuare and that the number increased (or decreased) by 10 is also a perfect square. And if you do not limit it to perfect square then every non-negative number is a square with the number that is 10 more also being a square.
