Question 1 (iii)
Find the square roots of each of the following numbers by Division method:
3481
3481
595¯¯¯¯¯¯34 ¯¯¯¯¯¯81−25109981−981 0
Steps
Step(i)3481 is dividend. Pair it in groups of 2 digits i.e ¯¯¯¯¯¯34 ¯¯¯¯¯¯81
Step(ii)Now for divisor,find the perfect square which is not greater than 44 which is 25(52)<34<36(62)
Step (iii)andNow take 6 as divisor and
55¯¯¯¯¯¯34 ¯¯¯¯¯¯81−251099
Step(iv)Now for new divisior double the old divisior and find a digit such that product of digit and the new divisor appended with that digit is the biggest number not greater than the new dividend and perform the division (109×9=981)
109981−981 0
Hence, the square root of 3481 is 59.
