How to easily find square root of a number?

Expert Answer:

You can find a number whose square will  be nearest to the number whose square root you are looking for.

Let's say, we take a large number 570 to find it's square root.

To start with we at least should know the square of the numbers uptil 30.

242 = 576; so 23.95 or so will be a good answer for square root of 570. Again how close is it? you can verify by carrying out the multiplication.

Hope this will help.
