I am having trouble with this question

Question

Which of the following is the value of log_b(1/b³) for any base b>0?

1) 3b

2)-3

3)1/3

4)b/3

Answer 1

None of the answers are correct.

LOG_b(1/b^2) = Log_b( b^(-2)) = -2

Answer 2

Perhaps there is a typo in the question?

If it was really log_b(1/b³), then

log_b(1/b³) = -3 log_bb = -3(1) = -3

Then answer choice (2) would be correct. Either way, the question is stated incorrectly, or the choices are stated incorrectly.
