Question

write any two methods two find a square root​

Answer 1

Answer:

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".)

Answer 2

Answer:

The numerical value of square root 2 up to 50 decimal places is as follows: √2 = 1.41421356237309504880168872420969807856967187537694… At present, the root 2 value is computed to 10 trillion digits. For general use, its value is truncated and is used as 1.414 to make calculations easy.
