Answer:
[tex]\sqrt{63}[/tex]
Step-by-step explanation:
We have to remember while answering this question that the square root of 64 is 8. Since the number on the number line looks like it's a little under 8, the answer can't be anything greater than the square root of 64.
The square roots of 66 and 65 are greater than the square root of 64, since they are both greater than 64, and 64 itself has a square root of 8, so it can't be the number.
The square root of 63 is our only option left, so it has to be the answer.
