FIND THE SQUARE ROOT OF 100 BY REPEATED SUBTRACTION METHOD

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

total no. of steps taken = 10

therefore square root of 100 is 10

Square root of 100 through repeated subtraction :
(i) 100-1=99
(ii) 99-3 = 96
(iii) 96-5 = 91
(iv) 91-7 = 84
(v) 84-9 = 75
(vi) 75-11 = 64
(vii) 64-13 = 51
(viii) 51-15 = 36
(ix) 36-17 = 19
(x) 19-19 = 0
Since we have subtracted 10 times, therefore sq. root of 100=10
