shruti dear

this is one method listed on most of the sites

so i m giving this:

check it out:

Here's one method for doing so.
If you're good with
long division, here's a quick way to find pretty accurate square roots
without the aid of a calculator. Let's try 24.6.

Make a guess. It can be a very bad guess. It doesn't matter. You can even guess 1. Let's try 5 since 5² is 25, which is pretty close to 24.6.
Divide 24.6 by 5. 24.6 / 5 = 4.92.
Now, comes the trick: Pick a new guess between 5 and 4.92 and divide it into 24.6 again. Let's try 4.95. 24.6 / 4.95 = 4.96. 4.96 is pretty close to 4.9598 which is the actual square root of 24.6.
Repeat steps 2 and 3 to any desired level of accuracy. The
further you go, the harder the long division becomes. But the first few
cycles yield a pretty close answer.

The reason this works is because n*n = 24.6 and n = 24.6 /
n. Therefore, the real square root will always be somewhere between
24.6 / n and n.
