Answer 1

between eight and nine.

Answer 2

`8<√(66)<9`

Explanation:

We are asked to find two consecutive whole numbers that square root 66 lies between.

We know that square root of 64 is a whole number that is 8 and square root of 81 is also a whole number that is 9.

`√(64)<√(66)<√(81)`

`√(8^2)<√(66)<√(9^2)`

`8<√(66)<9`

Therefore, square root of 66 lies between 8 and 9.
