The most obvious answer here is to simply take it's square root, and see if the answer is an integer. If it is, then your number is a perfect square. If you don't know it's square root offhand and don't have a calculator handy, you could do it by adding up a series of odd numbers, and seeing if they reach a sum that is equal to the original number. If they do, then you have a perfect square. Otherwise, you don't. For example, is 36 a perfect square? Let's find out: 0 + 1 = 1 1 + 3 = 4 4 + 5 = 9 9 + 7 = 16 16 + 9 = 25 25 + 11 = 36 Since we hit 36 with our addition, we know that 36 is indeed a perfect square.

Because numbers are infinite, there is an infinite number of answers. e.g. What number should be added to 2 to make a perfect square? 2+2=4 (a perfect square) 2+7=9 (a perfect square) 2+14=16 (a perfect square) 2+23=25 (a perfect square) etc... Did you have a specific number in mind.
Take the square root of 1617 and round it up. Take the square root of 5929 and round it down. That gives you the lower and upper range of the numbers which you must square to get the desired perfect squares.
