Answer:

#8.252272... ~~8.25#

Explanation:

To the nearest 'hundredth' is the same as saying
'Round off to two decimal places'

TO do this you first have to determine the answer with a calculator to at least 3 decimal place.

#sqrt68.1 = 8.2color(red)(5)227...#

The rounding will happen at the 5. It will either stay 5 or round up to 6, depending on the next digit which is a 2.
The 2 is below 5, so the answer rounds down to give:

#8.25#
