Question

How should we do square root for decimal numbers

Answer 1

To extract the square root of a decimal number, peform the following steps: 1Separate the number into two groups from the decimal point (the integer part and the decimal part).
 2 If the radicand has an odd number of decimal digits, add a zero to the right. 3.Disregard the presence of the decimal point and extract the square root of the resulting number.
4 In the root, from the right, place as many decimal numbers as there are a number of pairs of decimal places under the radicand. In the remainder and also from the right, place as many decimal numbers as there are decimal places under the radicand.
