Question

3. Find the square roots of 100 and 169 by the method of repeated subtraction

​

Answer 1

Answer:

ampere is the si unit of current

Answer 2

100 - 1 = 99. 99 - 3 = 96. 96 - 5 = 91. 91 -7 = 84. 84 - 9 = 75. 75 - 11 = 64. ...We get 0 at 10th step. Hence,10 is the square root of 100.√100 = 10.√169 by Repeated subtraction:169 - 1 = 168. 168 - 3 = 165. 165 - 5 = 160. 160 - 7 = 153. 153 - 9 = 144. ...We get 0 at 13th step. Hence,13 is the square root of 169.
