Answer 1

Hi ,

Square root of a perfect square by
___________________________
the long division method:
____________________

1 ) Group the digits in pairs, starting

with the digit in the units place.

Each pair and the remaining digit is

called a period.

2 ) Find the largest number whose

square is equal to or just less than

the first period. Take this number as

3 ) Subtract the product of the divisor

and the quotient from the first period

and bring down the next period to

the right of the remainder. This

becomes the new dividend.

4 ) Now, the new divisor is obtained

by taking two the quotient and

annexing with it a suitable digit which

is also taken as the next digit of the

quotient chosen in such a way that

the product of the new divisor and

this digit is equal to or just less than

the new dividend.
