Question

Identified the two consecutive integers in which each square root lies between.

Answer 1

1-  $\sqrt{156}$

156 lies between 144 and 169

So $\sqrt{156}$ lies between 12 and 13.

2-  $\sqrt{320}$

320 lies between 289 and 324.

So $\sqrt{320}$ lies between 17 and 18.

3-  $\sqrt{249}$

249 lies between 225 and 256

So $\sqrt{249}$ lies between 15 and 16.
