I have the question "What is the logarithmic form of the equation e^3x ≈ 3247?"
but I don't know what e is supposed to mean.

e is a letter that stands for a famous number. But (like pi) this number goes on forever see http://www-history.mcs.st-andrews.ac.uk/HistTopics/e_10000.html for some of its digits. Because it goes on forever, it is inaccurate to just write a few of the digits. Instead, people gave it a name "e'"

Wait I'm pretty sure e equals 2.7182818, the natural log (ln)

phi · Answer

yes, 2.718281828  is only the first few digits of e... and e is the base for the natural log

phi · Answer

for you problem, take the natural log of both sides of the equation

anonymous · Answer

okay so the answer would be  ln 3247 = 3x

phi · Answer

yes

Thanks! are you going to be on for a while? I may have more questions, because I'm struggling with this module and you explain everything a lot better than the "help" videos my teacher sent me when I asked her....

You can tag me if I'm not on... I'll (mostly) be near the computer.  

But, yes, logs are confusing,  more confusing than most things in math.
