g) Hence it has been compensated. Thus, leave the remainder. You get 36 as
the square root of the number 1296.


C. Example : 4225


a) Set the number 4225. Ask : What is the highest perfect square in 42. By
saying 36, set the square root of 36 in the left of 4225.


b) Subtract 36 from 42. Hence you will be left with 625. Now double the 6 and
set in the extreme left.


c) Now take 12 of the answer and 625 which is to be divided. Take the first digits.
How many 1’s in 6. Though it is 6, reduce 1, and therefore, it will be 5.


d) Set the 5 to the right side of the first digit of the square root and make it 65.
Set the 5 to the right and make it 125. Now multiply 5×125 and subtract it
from 625. You will not get any remainder. Thus the assumed quotient 5 is
the actual quotient.


e) That is, the square root of 4225 is 65.
