Ok, I have a project i have to do in math class. Like really MATH CLASS. Ok, now I need to figure out a word problem for a cubic root to a power for example:

^3√8^4

(In words what number cubed equals eight, and then do eight to the fourth)..

I need to put something like that into a word problem and It has to be multi step like my example. So please help me, preferably quick! I googled around a lot and I couldn't find one word problem.

What do you mean by "and then do eight to the fourth?
x^3=8.
x=2
or
x^3=8^4
x=cube root of 4016.
or
whatever it is you mean.

Umm, no, I want a word problem like, Sally has 4 apples she eats 2 now how many are left?
Thats what I need...

Wolfram|Alpha can't help you, but I'll try to.
Hmm...
^3√8^4...
What's supposed to be raised to the power of three? hmm

I guess that equation means the cube root of 8 raised to the fourth power. And I have no idea for a word problem involving it. Maybe check that section in your book and derive your question from a word problem there?

Errr, ok, but my math book is about as helpful as a rusty ceraded spoon.

A population of mosquito squirrels is rising rapidly. In order to stabilize the ecosystem, special hunters have been given permission to fire diminishing lasers at the mosquito squirrels. Each shot cube roots their population. However, after every shot, the mosquito squirrels rapidly reproduce to the fourth power of their population after getting cube rooted. After three such cycles, there are now 18446744073709551616 mosquito squirrels. How many were there before the shooting started?

Sorry if it's too weird hmm

Is this what you mean:

Sarah has some apples in a crate. If Sarah raised the number of apples by three, she would have 8 apples. How many apples would she have if she multiplied her current number by itself 4 times? How many apples did she have in the beginning?

I have a feeling that I missed your point. Can you please elaborate on the requirements of the problem?

Not a very effective stabilization idea. There's trillions of them now. tongue

It's a bit weird (and slightly illogical) but I suppose it would work as long as the teacher doesn't care if the word problem is actually applicable in actual life...

Lol thanks every body, I'm pretty sure that with all your problems combined I can do this!

miggle101 · 2010-09-09 21:41:12

Thanks every body, I used hpotter's word problem but antimon's was good but too elaborate, but thanks again and you really helped a lot, if you would allow it I would like to become your friends (after I finish this project, of course).

I'm logging off, I've been working for hours...yep...

hpotter? But his didn't have to do with cubic roots...
Oh. I guess you changed the calculations and stuff. Ok then.

You're welcome! smile

I'm in 8th grade, and I can't figure this out sad

Darn, I missed a math problem! tongue

I know you have an answer, but I'll make one anyway...

Jose has a magic cube made of 8 smaller cubes. Then, (abracadabra!) the width, length, and height each multiply by themselves four times! How many cubes wide is it now?

OK, that was lame. tongue I'm tired...

Hard to believe what?

Of course, my precalc teacher this year is a harsh grader, so she probably won't offer extra credit sad
