what question can be asked to help evaluate log3 81

Question

solomonzelman · Answer

No question needs to be asked.


$$Log_381$$
$$Log_3(3^4)=?$$

solomonzelman · Answer

Or my guess to what question can be asked,

What identities should be used to evaluate it?

solomonzelman · Answer

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

turingtest · Answer

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 $x$?"

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

turingtest · Answer

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.

Yeah...
