Question

find the square root of 100 thought report subraction and method.​

Answer 1

Answer:

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.
