The square root of a number is the value that, when multiplied by itself, equals the original number. The square root of a non-negative number is always a non-negative value. The symbol used to represent square root is √.

For example, the square root of 16 is 4, as 4 multiplied by itself equals 16. Similarly, the square root of 25 is 5, as 5 multiplied by itself equals 25.

To find the square root of a number, you can either use a calculator or manually through a process called long division.

Here is an example of finding the square root of 64 manually:

1. First, we pair the digits from the right end of the number. For example, for 64, we pair 6 and 4.
2. We find the largest perfect square that is less than or equal to the first pair of digits. In this case, 6 is not a perfect square, so we go with 4, which is the largest square that is less than or equal to 6.
3. We write down the square root of this perfect square. So, in our case, the square root of 4 is 2, so we write down 2.
4. We subtract the perfect square from the first pair of digits. In our case, 6-4=2.
5. We bring down the next pair of digits to the right of the remainder. So, we bring down 4.
6. We double the previously calculated square root and write it down next to the remainder. In this case, we double 2 to get 4.
7. We determine the largest digit that can be placed in the blank such that the product of the resulting number and the digit is less than or equal to the current remainder. In our case, we have to find the largest digit that, when multiplied by 44, is less than or equal to 24. We find that 5 is the largest digit that satisfies this condition.
8. We write down this digit next to the doubled square root from step 6 to form the next pair of digits of our square root. So, in our case, we write down 25.
9. We repeat steps 4 to 8 until we get the desired level of accuracy.

So, in our case, we get the square root of 64 to be 8.
