It's 9.95 . I did it within few seconds.

Let me tell you an interesting method for finding out square roots without using pen and paper within seconds and that to accurately.

Let P be the number whose square root is to be calculated.

Steps for calculating square root:

Search a perfect square number near about P. Let it be Q.

Now all you have to do is just to apply a magical formula and that's it. Here is the formula.



Let us try this formula to calculate the square root of 99.

So what is ‘P' here? It is 99

What about ‘Q'? It's 100.

After applying magical formula.
