When you square a number, you multiply it by itself and the result is the square of that number.When you take the square root of a number, you start with an number and figure out what smaller number would produce your starting number if it were to be multiplied by itself.
No, not always since: if a number is more than 1, then its square root is smaller than the number. if a number is less than 1, then its square root is bigger than the number.
It is if the number is more than ' 1 '. If the number is less than ' 1 ', then it's smaller than its own square root.
You try if the number is divisible by any smaller number (except one). If it isn't, it is a prime number. In practice, it is enough to test divisibility by factors up to the square root of the number.You try if the number is divisible by any smaller number (except one). If it isn't, it is a prime number.

You cannot. If you are dividing any square into equal sized squares, then the number of these smaller squares must be a square number.
