Well, the square root of 82 is an irrational number, so
it can never be completely written with digits.  As a
decimal, it goes on and on forever, and never ends. 
As a fraction, it can't be written at all.

The square root of  82  is approximately  9.055 .

(That number is about  0.0043%  too small, which is pretty close.)
