Any formula to Find Square Root?

Answer 1

U can find it fast using differential formula. But normally it will not be accurate. Depends on where ur going to use this calculation. If it is for fast calculation then u can use it.

To find diffential formula, what u need to do is

Example 1: If you want to find root of 5 then, here are the steps
1) Find the nearest square root value (root of 4 = 2)
2) Find the diff between 5 and 4 = 1
3) Then divide 1 by (twice of 2) = 0.25
So the value = 2+0.25 = 2.25

Example 2: If you want to find root of 12 then, here are the steps
1) Find the nearest square root value (root of 9 = 3)
2) Find the diff between 12 and 9 = 3
3) Then divide 3 by (twice of 3) = 0.5
So the value = 3+0.5 = 3.5

Answer 3

to find square root,

for eg.to find square root of 9

9-1=8------------------>a
8-3=5------------------>b
5-5=0------------------>c

the given number should be subtracted with 1and then from the answer the next odd number of before should be subracted until zero comes and then count how many times u have did this process that will be the square root of the given number.here in eg 3 times the process has been done .so the square root of 9 is 3

Answer 4

You should really find a calculator with square root on it.
This one is an online calculator for square root which i use when I can not find objects that wonder off.lol

This one give you different theorums and methods

and here is another good site for methods

I had that just last semester so I feel your pain lol.

Answer 5

learn vedic mathematics you will come to know the formula not only for finding square root but also of Nth root of any number without using calculators or any calculating device.

Answer 6

There are no "formula" to extract a square root, but you can do it by hand.
Check with your math teacher, the pocedure is a bit long to explain (similar to a long hand division, but using two digits at each stage).
Otherwise, use your calculator!

Answer 7

what does the mean of divide 3 by twice of 3
