Question

what question can be asked to help evaluate log3 81

Answer 1

No question needs to be asked.


\[Log_381\]
\[Log_3(3^4)=?\]

Answer 2

Or my guess to what question can be asked,

What identities should be used to evaluate it?

Answer 3

\[\log_381=\log_3(3^4)=4\log_33=?\] can you continue, or should I ?

Answer 4

I actually do like to phrase logarithms in the form of a question. For example, evaluating something of the form\[\large \log_bx\]is equivalent to the question "\(b\) raised to what power equals \(x\)?"

Answer 5

Maybe, I typically think ...or I don't think, I just do it (when it comes to logs) :)

Answer 6

Once you are comfortable with logs, you probably shouldn't get too hung up on that interpretation, but I think it's a valuable interpretation to keep in mind for a beginner.

Answer 7

Yeah...
