I little bit confused by your problem JK, is it like this?
\[\large \log_{1/3}(9)\]
With a base of 1/3?

Answer 3

yes...could the answer be y=-2

Answer 4

\[\large \log_{1/3}(9) \qquad = \qquad \log_{1/3}(3^2) \qquad = \qquad \log_{1/3}\left(\frac{1}{3}\right)^{-2}\]

-2? Yes very good! :)

Answer 5

what about
[\log_{10} 1/1000\]

would it be -3

Answer 6

log 1/1000

understood 10

Answer 7

\[\large \color{royalblue}{\log \frac{1}{1000}} \qquad = \qquad \color{royalblue}{\log 10^{-3}} \qquad = \qquad -3\color{royalblue}{\log 10} \qquad = \qquad -3\cdot \color{royalblue}{1}\]
Yes, good job.

Answer 8

and \[\log_{2} \sqrt{1/2}\]

would be -4??
