Q.3 Find the square roots of and by the method of repeated subtraction.
(i) For 100 :- 100 - 1 = 99
99 - 3 = 96
96 - 5 = 91
91 - 7 = 84
84 - 9 = 75
75 - 11 = 64
64 - 13 = 51
51 - 15 = 36
36 - 17 = 19
19 - 19 = 0.
We obtain zero at 10th step so
(ii) For 169 :- 169 - 1 = 168
168 - 3 = 165
165 - 5 = 160
160 - 7 = 153
153 - 9 = 144
144 - 11 = 133
133 - 13 = 120
120 - 15 = 105
105 - 17 = 88
88 - 19 = 69
69 - 21 = 48
48 - 23 = 25;
25 - 25 = 0.
We obtain Zero at the 13th step so
