Question

`144 < n > 225`
What can you say about √N?​

Answer 1

The square root of n is between 12 and 15.
If n is larger than 144 (12x12) and smaller than 225 (15x15), the square root of n has to be in between 12 and 15.
If you are only talking about integer square roots, then the square root n has to be 13 or 14 (169 or 196 respectively)
