What is the solution to the equation log (3) x – log (3) 2 = 2 ?

x = 18

x = 12

x = 9/2

x = 4/3

You need to figure out how to represent 2 as a log with base 3. So Log(3)x=2 Well, 2^3 =8 so x is 8. 

You now have log (3) x - log (3) 2 = log (3) 8
You can take out the log(3) now.
x-2=8
And I think you can get it from there.

Thats not an answer choice though? I got x=10

what? this makes no sense

I'm an idiot.

Log(3)x-Log(3)2=2
Log(3)(x/2)=2
3^2=(x/2)
9=(x/2)
18=x

Don't even ask what I was thinking.
