How to find Square Root

How to find square root of 5 digit number, square root of 4 digit number or square root of any number without calculator has now become very easy. To find square roots you need to remember certain things that will help you find square roots quickly.

Let’s take a look,

The tricks to find square roots in seconds you have to remember this chart.

Number	Square	Last Digits
0	0	0
1	1	1
2	4	4
3	9	9
4	16	6
5	25	5
6	36	6
7	49	9
8	64	4
9	81	1

Now Carefully see the the following chart to find how square roots are derived.

Note that in 5^th column, if (d) that is the value of (c)*(c+1) is greater than the first two digits of the example [28 in the example 2809 or 50 in the example 5041] that is 30>28 or less than the first two digits of the example that is 72<73 in column 6^th, then the last digit of the answer will be accordingly, derived from the 7^th column (f) of the chart.

So this is how the square of any number is derived quickly even without calculator. One suggestion, the more you practice the more quickly you can calculate square roots.
