Question 430035
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.....
