I'd give a medal for the best answer :3

Do exactly what the instruction says.  In 9log(x), replace x by 8 and that will be your answer.

anonymous · Answer

alright i got 8.127. hopefully thats the right answer. thanks again!

Sometimes just 9log(8) will be an acceptable answer.  Sometimes they expect you to evaluate using a calculator and provide them with a number.  So the answer depends on what form they are expecting here.

oh well they wanted my answer to be a decimal and i was told to round it to 3 decimal places.

aum · Answer

9log(8) = 8.127809....
If you round to 3 decimal places, it is 8.128   (not 8.127)
