Technically 0, 9 and 16 qualify. Add any two together and they still make perfect squares (i.e. numbers whose square roots are integers).
I couldn't find any others < 625 or 252
41, 80 and 320 work!

Also, 17, 32, and 32

To determine if 224 is a perfect square, we need to find its square root. The square root of 224 is approximately 14.96. Since the square root is not a whole number, 224 is not a perfect square. Perfect squares are numbers that are the result of an integer multiplied by itself, such as 9 (3x3) or 16 (4x4).
There is no limit to the number of perfect squares. To find a perfect square, you simply need to pick a number and square it. E.g. 7^2=49, so 49 is a perfect square. As there is infinitely many numbers to pick, and as the larger a number the larger it's square, there are infinitely many perfect squares and they just keep on getting larger!
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.
If its square root can be expressed as a rational number then it is a perfect square. 9075 is not a perfect square. However, 9025 is.
create a program that iterates until it finds a perfect number, then store that perfect number into an array. Continue iterating until you find three more. Then, you have an array of four perfect numbers.
say u have the number 16. Its square root is 4. the square root(4) is the number that, when multiplied by itself, gives the original number (16). To find a square root you must first find the two closet perfect squares (a square being the product of a square root, a perfect square being the product of square roots that are whole numbers 1,2,3,4, ect.) then u find the approxomate distance between
sqrt(30)= 5.5 approx sqrt(40) = 6.3 approx The integer 6 is between the square roots. So the square of 6, which is a perfect square, will be between the two original numbers. So answer is 62 = 36.
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.
5607 + 18 = 5625, a perfect square. The perfect square of a square root is the number you started with.

There are a total of 5 positive three-digit perfect cubes that are even. To find this, we first determine the range of three-digit perfect cubes, which is from 46 to 96. Then, we identify the even perfect cubes within this range, which are 64, 216, 512, 729, and 1000.
