5006 = 1000(1.01)12 (1.01)n

5006/1000(1.01)12 = (1.01)n


Does that help?

Yep.

5006 = 1000(1.01)12 (1.01)n would be the case if the original equation were 5006 = 1000(1.01)12+n

In this case you want 5006 = 1000((1.0112)n)

Which would be 5.006 = ~1.127n

I think.

You guys are exactly right and I realized my error earlier this evening.  Sorry dude.  Wish I'd caught it before everybody else did.

5006=1000(1.01)^(12n)

like... um

5006^(1/12)= 1000(1.01)^n   right?  something like that... I'm a tryn' to express 12 root or some such

(5006^(1/12))^(1/n)= 1000(1.01)

(whatever)^(1/n)= wutuvu       (too lazy to do the math on those.  who the fnck cares anyway ,right?

(whatever)^(1/n)= wutuvu      and then from here, it's something to do with that thing where recipricoals in exponentials can magically move to somewhere else if reciprocolated...  I forget the details exactly but if you're reading this then you probably know what I mean.

Ah, umm, yes. I hope I didn't make it seem like I was saying "that doesn't help because it is incorrect." What I meant to say is "NO WAY THAT SHIT'S INSANE, IT'S ALL CHING CHONG WING WONG"

I don't want to give the impression I would be able to to correct an error in a math problem. But good job Oball.

To be fair I can't remember any of that stuff and I had to look up the exponent rules on Wikipedia.

Hell, when I was in college we just wrote a letter to Leibniz and asked him for crib notes.
