Question

Find the square root of 100 and 169 by the method if repeated substraction​

Answer 1

Answer:

Step-by-step explanation:

=> √100 by Repeated subtraction:

100 - 1 = 99. 99 - 3 = 96. 96 - 5 = 91. 91 -7 = 84. 84 - 9 = 75. ...

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.
