A perfect square is the square of an integer, i.e., an integer multiplied by itself. For example, 25 is a perfect square, because 5 x 5 = 25.
But, in literal mathematical terms, a perfect number is a positive integer that is the sum of its proper positive divisors, excluding the number itself. A square number is also called a "perfect square", so an example of a square number is above.
So, a perfect square number would have to be a number that is both perfect and square, and there are yet to be any of these numbers "discovered".

β 13y agoBecause 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.
you can multiply two whole numbers together to get that. if you use graph paper, you could make a perfect square. the area of that square is called a perfect square because you can make a perfect square using that many units as the area. for example 4x4=16, so 16 would be the perfect square.
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
You take the square root of the number. If it is a perfect square, this will be a whole number. If it is not, it isn't a perfect square.
Well, technically, it is the square of 11.18033989...but it is not a perfect square(a perfect square is the square of a whole number. 1,4,9,16,25,36,49,64,81,100,121,144,169,196,225,256, etc.)

5607 + 18 = 5625, a perfect square. The perfect square of a square root is the number you started with.
For a number to be a perfect square, the number's square root has to be a whole number. 9 is a perfect square because its square root is a whole number, 3. If the square root of the number is a decimal, then it is not a perfect square. For example, 13 does not divide evenly so it not a perfect square.

It is 2 times 18 = 36 which is a perfect square number because 6 time 6 = 36
20 is a not perfect square.
