Answer:

1.2262943855309168262595...

Step-by-step explanation:

You use the change of base formula:

[tex]log_b(a) = \frac{log_c(a)}{log_c(b)}[/tex]

So in essence, you can take any base c and just divide by the log of the original base b.

A special base is e, which gives you the natural log ln.

So even ln 9 / ln 6 gives the same answer.
