Answer:
How to find....
Step 1: First group the digits in pairs, starting with the digit in units place. Each pair and the remaining digit (if any) is called a period.
Step 2: Think of the largest number whose square is equal to or just less than the first period. Taking this number as a divisor and also the quotient.
Step 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 makes a new dividend.
Step 4: Now, the divisor is obtained by taking two times the quotient and annexing the suitable digit which is also t when as the next digit of quotient, chosen in such a way that the product of new divisor and the digits are equal or just less than the new dividend.
Step 5: Repeat steps (2), (3), (4) till all the periods have been taken up. Now the quotient so obtained is the required square root of the given number.
