Respuesta :

between eight and nine.

Answer:

[tex]8<\sqrt{66}<9[/tex]

Step-by-step 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.

[tex]\sqrt{64}<\sqrt{66}<\sqrt{81}[/tex]

[tex]\sqrt{8^2}<\sqrt{66}<\sqrt{9^2}[/tex]

[tex]8<\sqrt{66}<9[/tex]

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