Can a square number end in any digit?
No, a square number cannot end in just any digit. Specifically, the last digits of square numbers can only be 0, 1, 4, 5, 6, or 9. This is because when you square integers, the resulting last digits are limited to these values based on the last digit of the original number. For example, squaring a number that ends in 2 gives a last digit of 4, while squaring a number that ends in 3 gives a last digit of 9.

What digits do square numbers end in?
Square numbers can end in the digits 0, 1, 4, 5, 6, or 9. This is because when you square the last digit of a number (0-9), only these digits appear as the last digit of the resulting square. For example, squaring 2 gives 4, squaring 3 gives 9, and squaring 5 gives 25, which ends in 5. Thus, any square number will always end in one of these six digits.
