The square root of 72 is an irrational number and there is no such thing as a best approximation for any irrational number. By definition, all Irrational Numbers are represented by infinitely long decimal strings and it is always possible to improve the approximation by calculating the value to one more decimal place.
8.48528 should be sufficiently accurate for most purposes.

The square root of 72 is equivalent to 6 times the square root of 2.
Well, there technically is not a way to simplify the square root of 2, but the simplified version of the square root of 72 is 6 square root 2
36
6 root(2) = root(36) root(2) = root(36 x 2) = root(72).
The best approximation is, of course, the exact value. A reasonable approximation is 106.

Yes, it does.
Rounded to two decimal places, the square root of 72 is 8.49.
The square root of 72 is an irrational number. Since 72 is not a perfect square, the decimal is endless. (just like the value of pi)
