anonymous · Answer

these are thee answers 
f(x) = logx 5 

 f(x) = 6 log x 

 f(x) = log 6x 

 f(x) = log6 x

Can you rewrite your answer possibilities with the equation tool so we can completely understand. There are some ambiguities.

anonymous · Answer

no there is no power signs or anything its correct for sure.

anonymous · Answer

Are the log's all base ten, besides the last one?

anonymous · Answer

wait i think i found out what you ment here the number closer to the log sign is a base and the farther one is just regular

anonymous · Answer

Do me a solid and just rewrite them using the tool.

anonymous · Answer

$$\log _{x}5$$
$$6 \log x$$
$$\log 6^{x}$$
$$\log _{6}x$$

anonymous · Answer

Thank you. All you need to do is guess and check. Plug in the value of x for each possibility and see if it gives you the f(x) value you're looking for.

This is how you solve logarithms of any base. http://www.purplemath.com/modules/logrules5.htm This, and a calculator, will do the trick.
