FIND THE SQUARE ROOT OF 100 BY REPEATED SUBTRACTION METHOD

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

FIND THE SQUARE ROOT OF 361 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 So simple

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

no. of steps = 10
so the square root of 100 is 10

the above answer is right
