Question

Which of the following is the solution of log x – 5 0.001 = –3 ?

Answer 1

the x-5 in small behind the log

Answer 2

could you use the equation tool to clarify what the problem is?

Answer 3

I don't know what the equation tool is?

Answer 4

\[(x-5)\log(0.001) = -3\]is that your question?

Answer 5

yeah

Answer 6

okay, well when you have log, just written like that, it's in base 10.
So first, calculate what's the log of 0.001 in base 10.

Answer 7

-3

Answer 8

okay, so then you have
-3(x-5) = -3

so it's just a simple problem of finding x :)

Answer 9

@sarahcoop3r did you get it?

Answer 10

I got -4

Answer 11

which isn't an option for me....

Answer 12

oh. weird.. what are your options?

Answer 13

5,7,13 and 15

Answer 14

wait, how did you get 4?
you just do:
(x-5)=(-3/-3)
so x=6.

weird. i dunno, unless the question's been written wrong, my best guess would be to put in 5 as the answer.
