Help, have a math question.

[WilliamPitt]

I am hopeless at math.

I need to know how many orders of magnitude 11,111 is from 208. How many orders of magnitude have to be added to 208 to get 11,111? Any? Whatever answer you come up with can be a rough estimation. I don't need an answer to the decimal.

Thanks.

1. That's a math question?

Wow. I wasn't paying attention in high school. Is it calculus?

Whatever the matter, good luck!

5. :D

:rofl:

2. 2 isn't it?

11111 = 5 positions
208 = 3 positions
difference of two.

[billyskank]

3. What base does he mean?

:evilgrin:


No, you're right of course - it's two orders of magnitude

[mainegreen]

8. Thats true, if we convert 11111 to base 10 we get 31 which is -1 orders

differece.

If you're feeling saucy that is.

4. Approx 1.5 orders of magnitude

quick solution is how many steps you have to move the decimal

15. My dear TexasRazor!

Welcome to DU!

Have fun in our crazy, addictive little village!

20. Thanx Peggy

The water's fine !

6. It will take Jimmy 2 Hours By Train or 4 Hours By Bus

:shrug:

7. ANOTHER MATH QUESTION, similar

How many orders of magnitude have to be added to 623 to get 40,000?

9. It will take Jimmy 8 Hours By Donkey or 6 Hours By Moped

again. :shrug:

10. You don't add orders of magnitude

you multiply by them.

208 is two orders below 11111 because 208 x 10 x 10 = 20800, and 20800 is the same order as 11111.

[billyskank]

14. The exact answer is this:

208 x (10 ^ n) = 11,111

therefore:

10 ^ n = 11,111 / 208

so we can say:

10 ^ n = 53.42

So n = log(10) 53.42

= 1.73

So you need to raise 208 by 1.73 orders of magnitude to get 11,111. Roughly.

18. Wow billyskank, I love it when you

talk dirty....

11. Generally that's 2 again

Otherwise just use a ratio.

12. I would say 50

although its 53. something. Although I am a math major I am not that familiar with the term, although it sounds like division would do it as in 11,111 is 53 times 208, although for rhetorical purposes one could say 'over 50'.

[mainegreen]

13. 50? What are they teaching you over there?

17. shoulda known wiki would have the answer

as I said, I was not familiar with the term, and my schooling is way in the past. It is more a terminology question than a math question, and the dictionary was no help.

Over there? We are on the same side of the Mississippi, or we were, just barely.

16. THANKS, ALL

My math-addled brain thanks you all. :)
