How do you find the square root of a number without using guess and check or a calculator?
For simplicity, let's take a four digit number 4096
Starting at the right, mark off the digits in pairs: 40'96
The highest number whose square does not exceed 40 is 6 so deduct its square from 40, leaving 4, now bring in the 96 making 496. 6 is the first digit of the solution
Add another 6 to the 6, making 12, but call it 120. Now find a number you can add to 120 and multiply that by your new number to make 496. This number is 4 which works out exactly so the square root of 4096 is 64.

How do you check if a number is a perfect square?
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.
