Okay, apparently I'm horrible at math because I cannot figure out this problem that's on a summative assignment we have to do. Could someone explain it to me?

Basically, it comes down to this:

54,032 = 1,000 x e^{r x 18}

I'm solving for r. Any help appreciated.

That is the reason why I don't have any math classes anymore.

[SlowPokemon]

Wait, seriously? That's too awesome. Unfortunately I still have to take them... >_>

[Roz~]

Yep. I'm that awsm.

[SlowPokemon]

Well, as a 22-year-old...

Well, you'll have to first divide 54,032 by 1000= 5,403.2
Then ln(e^{r x 18}) = ln(5,403.2)            You can put a ln on both side

ln(e^{r x 18}) = rx18 because ln(e) = 1 and when you have an exponent in a logarithm you can put it(the exponent) in front of the log.
So this bring us to
r x 18 = ln(5,430.2)
r= ln(5,403.2) /18

Exponent*

But yes, that is correct above.  That's actually one of the most simple log problems possible, so you must have not been paying attention in class :|

I loved solving logs problems. Probably the only thing thing I enjoyed in my math classes, even though I sucked at it x)
Also exponent is exposant in French.

That's silly.  Mixing French and English terms like that makes it all confusinglike -.-

Yeah I'm not too familiar with math English terms, i'm sorry. Hope you still understood what i wrote

That's a simple continuously compounded interest equation. stuff i did in calc last quarter and stuff in finance!

[Jub3r7]

I also remember doing that last semester, which is the reason why I don't remember it at all...

[KefkaticFanatic]

Yeh, I did it in basic algebra II.

[DrP]

^Same... I was a sophomore falling asleep in the back of that class because it was so easy

You speak for the majority of us xD
