Log power of(3n-1) to base 10-Log power 2 to base 10 =3

we have discussed this before. It makes no sense. What is being taken to the power? log (x^(3n-1)) ? If you want to get help, you will just have to write in standard notation. As it is, the wording makes no sense. The base 10=3 makes no sense.

I have a sneaky suspicion that Ghazali means:
log <sub>10</sub> (3n-1) - log <sub>10</sub> 2 = 3
of course, if the base is 10 , the base is understood and
we don't even have to write it,
so is it
log (3n-1) - log 2 = 3 ???, if so then
log ( (3n-1)/2) = 3
(3n-1)/2 = 10^3 = 1000
3n - 1 = 2000
3n = 2001
n = 667
log <sub>10</sub> (3n-1) - log <sub>10</sub> 2 = 3
