Hi ,Square root of a perfect square by___________________________the long division method:____________________1 ) Group the digits in pairs, startingwith the digit in the units place. Each pair and the remaining digit iscalled a period.2 ) Find the largest number whose square is equal to or just less than the first period. Take this number as the divisor and as the quotient.3 ) Subtract the product of the divisorand the quotient from the first period and bring down the next period tothe 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 whichis also taken as the next digit of the quotient chosen in such a way thatthe product of the new divisor and this digit is equal to or just less than the new dividend.5 ) Repeat steps 2, 3and 4 till the periods have been taken up.*******************************************6 ) 39 06 25 ( 62536__________122 ) 306244_____________1245)52255225_________________0ThereforeSqrt (390625) = 625I hope this will useful to you.
