# 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;
