#### Square Root : Finding the square root of a number by estimating and multiplying can be a long procedure. Given below is a simpler method to find the square root of a number:

**Example:** **Find the square root of 2116**

To find the square root of 2116:

**Step 1:** See the digit at one’s place. In this case, it is 6. Now, check between 1-9, the square of what all numbers have “6” at one’s place. The answer is 4^{2 }= 16 and 6^{2} = 36

**Step 2:** Now check, the square of which number between 1 to 9 is closest to the first two digits of the given number. In this case, the sum of which number between 1 to 9 is closest to 21. The answer is 4^{2} = 16 and 5^{2} = 25

So, one number among 44, 46, 54 and 56 is the square root of 2116

**Step 3:** The two numbers you got in step 2, multiply each of them with the next number in the number series. That is, 4×5 = 20 and 5×6 = 30. Since 20 is a closer number to 21. The answer has to be either 46 or 44. Multiply and check your answer.
