Question

how to find root of any no

Answer 1

Your Answer :-)

What is the number you want to find the square root of? Here's one we'll use:

46656

First, divide the number to be square-rooted into pairs of digits, starting at the decimal point. That is, no digit pair should straddle a decimal point. (For example, split 1225 into "12 25" rather than "1 22 5"; 6.5536 into "6. 55 36" rather than"6.5 53 6".)

Then you can put some lines over each digit pair, and a bar to the left, somewhat as in long division.

+--- ---- ---- | 4 66 56

Find the largest number whose square is less than or equal to the leading digit pair. In this case, the leading digit pair is 4; the largest number whose square is less than or equal to 4 is 2.

Put that number on the left side, and above the first digit pair.

2 +--- ---- ---- 2 | 4 66 56

Now square that number, and subtract from the leading digit pair.

2 +--- ---- ---- 2 | 4 66 56 |-4 +---- 0

Extend the left bracket; multiply the last (and only) digit of the left-hand number by 2, put it to the left of the difference you just calculated, and leave an empty decimal place next to it.

2 +--- ---- ---- 2 | 4 66 56 |-4 +---- 4_ | 0

Then bring down the next digit pair and put it to the right of the difference.

2 +--- ---- ---- 2 | 4 66 56 |-4 +---- 4_ | 0 66

I hope it will help you..
