What?
73 = 343 which is the square of 18.52... hardly a perfect square!
The correct answer is 9.
No to be a perfect square you should be able to take the number and square root it on the calculator and get an integer.
No because its a cubed number 53 = 125No
No it is not. 22 is not a perfect square because it is not a product of a rational number multiplied by itself. The closest perfect square would be 25
1600 (square of 40)
Yes, 100 is a perfect square aka. a square number. It's pretty easy toidentify You just multiply a number by itself to get a square number for example: 4 is a perfect square because it has two repeating factors 2x2. If we take 64 as another example, 8x8=64. So 64 would be a square number. 10x10=100 So yes! :)
The smallest perfect square is 121.
6443 = 6482 = 64
Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
The first perfect square which is greater than 300 is 324.
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.

Actually it can, if it's not the square of a prime number. For example, 144 is the square of 12; but you can also factor it as 6 x 24.
20 is a not 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.
It is the definition of a perfect square.
