52 = 25 This a perfect square. Take the square root of each side and.... 5 = 5
No, consider 16 + 25 ...
It is not a perfect square. 5-square = 25 6-square = 36 So there cannot be a perfect square between 25 and 36.
A number multiplied by itself is a perfect square as for example 5 times 5 = 25 which is a perfect square
The square root of a perfect square is a whole number. Example sqrt(36) = 6 so 36 is a perfect square Example sqrt(25) = 5 so 25 is a perfect square Example sqrt(8)= 2.828 which is not whole so 8 is not a perfect square
