(2R cubed - 8)/9 = 120/9

so, what does R =?

(2R cubed - 8)/9 = 120/9

so, what does R =?

Still having trouble with Enigma?

Throw out the nines, since they're in the denominator on both sides.

Add eight to both sides to get 2R^3=128

Divide by 2 to get R^3=64

Take the cube root of both sides to get R=4.

Good luck with the puzzle!

You're really going to hate ?

(2R cubed - 8)/9 = 120/9

so, what does R =?

If I understand the question:

((2R)^3-8)/9=120/9

(2R)^3-8=120

(2R)^3=128

2R=5.0396841995794926590688424291129

R=2.5198420997897463295344212145565

or is it

(2(R^3)-8)/9=120/9

2(R^3)-8=120

2(R^3)=128

R^3=64

R=4

I didn't know if you are cubing 2R or just R.

I know the cache he is going after. R=4 is the correct answer.

I am afraid of math.

You need this...

Wow!

Another crypto cache to solve! But I don't know if I'll go find it tho. Is it at least no further north than let's say 20 miles of Racine?

It is within a few miles of the fake coordinates, somewhere in downtown Racine.

What the... The only thing i gathered from that is the ? picture is in .png format. Beyond that, I've got no clue.

Perhaps there is something more at the listed coordinates.

Yeah I was afraid that was the case... 2500 miles is a long way to go to find out

Especially if it requires a "quick" trip back home to dig out a calculator and the old high school trig/algebra/calculus textbook.

No math involved. There's something at the posted coordinates.

Something that might be useful here...

what is "here" It appears as though it is some kind of log-in....

Keep it up Cheese, and you just may have me on a road trip north.

Go find the cache first...

Cartesian Coordinates

Hm I think the answer is there some where lets go find a cache.

This is the one I was really looking for.

Common usage among mathemeticians says that 2R cubed mean Rcubed multiplied by 2. Exponents are computed before multiplication.

Just an old math teacher chiming in.

Ditto. It's called order of operations. Exponents first, then multiply or divide, last add or subtract.

Did you get the additional hint also? I think I'm thinking too hard about it.

I understand order of operations (I use to be a math minor and tutor). I wasn’t sure because of the way it was written in the question. To me at first it looked like 2R was to be squared not just R. This is why I have both of my interpretations of the problem. I realize it would have made more sense in a textbook.

I am afraid of math.

That's probably the best clue for your Key West cache I've read so far...

Now I know I'm way off...

Where's a 13 year old kid when you need one?

I still can't figure out the RM/2 thing at the gas pumps.....

Edited by TEAM 360

Yeah this is caching......

But have fun.

R! Please. I thought we'd getten the pirate thing out of geocaching! R!

Keep it up Cheese, and you just may have me on a road trip north.

Between Enigma and ? you should all come on up to Wisconsin and test your wits!!

When you're logging your find, don't forget to mention the forum folks who helped ya get it

Wow... the Folks posting in the forums! Welcome! ? Is the cache that I mentioned that I was going to call the Cheesehead Enigma until yours popped up. That's OK, as I like the new name better.

I just need to figure out how to pronounce it...

Wow!

I was kicked out of Wisconsin once, I don't think I'll be finding your caches anytime soon

R! Please. I thought we'd getten the pirate thing out of geocaching! R!

R! (R factorial)...egads this is difficult math...

Well, today, he's in school. But yesterday, he was at the cache.
