Question

Between which two consecutive integers is 80 to the negative square root?

Answer 1

Between `-9` and `-8`

Explanation:

`80` lies between `8^2=64` and `9^2=81`

Hence `sqrt80` lies between `8` and `9`

However, we ave both `8^2=64=(-8)^2` and `9^2=81=(-9)^2`

and hence `80` to the negative square root

will lie between `-9` and `-8`
