Similar example (using the formula campbell_st wrote) $\Large \log_{3}(7) = \frac{\ln(7)}{\ln(3)}$ $\Large \log_{3}(7) \approx 1.7712437$

coolaidd, with all due respect, your last three questions have involved very basic logarithmic rules, and you have not shown any growth between them. You'll need to make an effort here, or else we're all wasting our time trying to help you.
