Hi Students, In this video lecture we are going to learn Square Root of a 3-digit number that is by 729 using division method. As we are doing division method so we have to follow the following steps: • Step I: Group the digits in pairs, starting with the digit in the units place. Each pair and the remaining digit (if any) is called a period. • Step II: Think of the largest number whose square is equal to or just less than the first period. Take this number as the divisor and also as the quotient. • Step III: 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. • Step IV: 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, 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. • Step V: Repeat steps (2), (3) and (4) till all the periods have been taken up. Now, the quotient so obtained is the required square root of the given number. • • Students you can also follow us on Facebook • / tutoronline3 • #Exponents #SquareRoot #LongDivisionMethod
