SOLUTION: Hello, I am trying to find an answer using the Log function on the Windows scientific calcultor. The equation given to me is: Log 1000000 = 6 Log 1000 = 3 Log 1.01 = 0.00432 I see

Question 430035: Hello, I am trying to find an answer using the Log function on the Windows scientific calcultor. The equation given to me is: Log 1000000 = 6 Log 1000 = 3 Log 1.01 = 0.00432 I see how to do this. The issue is the following: I am told to put these values into the formula:
6-3
----- = 694
0.00432
I cannot figure out how to enter the formulas or what keys to press to get the answer 694. I have tried everything without success. I think my biggest problem is not understanding what actual buttons to push or sequence of numbers to get to the answer 694. Also I think I am misunderstanding the minus sign in between the 6 and the 3. I have noticed the 6 is raised higher than the 3 in the original equation. Sincere Thanks, Ande Lu

Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
log 1000000 = 6
log 1000 = 3
log 1.01 = .004321374 which appears has been rounded to .00432

you're told to take (6-3) and divide it by .00432 to get 694.

(6-3) = 3, so the equation becomes 3/.00432 = 694.

I do it on my calculator and i get 694.444444444

that rounds to 694, so i'm at least in the right direction.

using the windows calculator, you would do the following:

bring up the scientific calculator.

hit the following keys;

1 key once
0 key 6 times
log key once
- key once
1 key once
0 key 3 times
log key once
= key once
/ key once
1 key once
. key once
0 key once
1 key once
log key once
= key once

you will have done the following:

enter 1000000 and then hit the log key.
the result will be 6
hit the - key
enter 1000 and then hit the log key
the result will be 3
hit the equal key
the result will be 6 - 3 = 3
hit the divide key
enter 1.01 and then hit the log key
the result will be .004.........
hit the equal key
the result will be 3 / .004..... which will be equal to 694.....
