Any idea, how you would isolate x?

anonymous · Answer

not quite sure i suck at these things

anonymous · Answer

Well is there anything here you can eliminate right away?

anonymous · Answer

get x out by itself?

anonymous · Answer

Hint: $$a^b=c \implies \log_ac=b$$

anonymous · Answer

B?

anonymous · Answer

Well...try that and see what you get.

anonymous · Answer

My hint is actually the first thing you learn in logarithms, so this means, you need to review your rules.

anonymous · Answer

Look at my hint again and see what you can do with it.
