Answer:

Step-by-step explanation:Hi,

Square root:

The square root of a number is that number,

whose square is equal to the given number.

Long division method:

1 ) Group the digits in pairs, starting with the

digit in the units pkace .Each pair and the

remaining digit ( if any ) is called period.

2) Find the largest number whose square is

equal to just less than the first period.Take

this number as the divisor and as the quotient.

3) Subtract the product of the divisor and the

quotient from the first period and bring down

the next period to the rightnof the remainder .

This becomes the new dividend.

4) Now, the new divisor is obtained by taking

two times the quotient and annexing with it

a suitable digit which is also taken as the next

digit of the quotient chose in such a way that

the product of the new divisor and this digit is

equal to or just less than the new dividend.

5) Repeat steps 2,3 and 4 till the periods

have been taken up.
