The square root of 66 will be between 8 and 9, closer to 8. 8.1 is too low, 8.2 is too high. 8.12 is low, 8.13 is high. 8.124 is close enough.
7
The square root of 66 is a little bit greater than 8. So, plotted on a number line, it would be just to the right of the number 8.
The square root of 49 is 7 and the square root of 64 is 8 so it has to be between 7 and 8 (and it's probably closer to 7)

The square of 57 is 3249 The square root of 57 is closer to 8.
No. The square root of 8 will be between 2 and 3, much closer to 3.
Example: The square root of 54 The square root of 54 is not an integer, since 54 is not a perfect square. The square root of 54 will be between 7 and 8, since 54 is between 49 and 64. Since 54 is closer to 49 than it is to 64, the square root will be closer to 7 than 8. I'd estimate the square root of 54 to be approximately 7.35 The actual square root is plus or minus 7.3484692 To simplify a square root, search for any factors greater than one that are perfect squares. Since 54 = 9 x 6, the square root of 54 equals the square root of 9 x 6 equals the square root of 9 times the square root of 6. The square root of 9 is 3, so the square root of 54 simplified is 3 times the square root of 6.
The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.
