Respuesta :

The number would have to be in between 64 and 81, since those are the squares of 8 and 9.  So, choose a number greater than 64 but less than 81.
 
Hope this helps :)

Based on the fact that the square root of this number is between 8 and 9, the number must be between 64 and 81.

The square root of a number being between 8 and 9 means that the number itself must be between the squares of 8 and 9.

The square of 8 is:

= 8 x 8

= 64

The square of 9 is:

= 9 x 9

= 81

The number in question must therefore be between the numbers 64 and 81.
