You have been doing log problems for a while - you should know better.

You'll need to use a calculator and use the fact:

\(\displaystyle LOG_a(b) = \frac {LOG_{10}(b)}{LOG_{10}(a)}\)

If it looks like this... \(\displaystyle \log_3 0.942\) it means "log to the base 3 of 0.942."

Is there a way to work it without a calculator?

1n 0.942/1n 3

No ... not with those numbers ( you can use computer and spreadsheet like Xcel)
