Best Answer
The square root of 66 is irrational. There is, therefore, no "best" approximation since that depends on what level of precision you require.


In some cases 8.1 is sufficient, in other situations you may want 8.12404 and in some you may want even more precision.

What is the best decimal approximation for the square root of 82?

There is no "best" approximation. The square root is irrational and so it is a non-terminating, non-recurring decimal so adding one more digit will always make it a better approximation.

What is the best approximation for the square root of 72?

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.

In radical form, 3* sqrt(41). The decimal approximation is 19.20937271.


What is the best answer for the square root of 34?

The best answer is "sqrt(34)" since any rational or decimal representation must be an approximation. Any decimal representation can be improved by adding more decimal places. In practice, 5.831 is accurate enough.
