No. Though every perfect square is a rational number, not every rational number is a perfect square.

Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.

What number can be increased or decreased by 10 and you will still have a square number?

"Still" implies that the original number is 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.
