Question

solve for all valid values of x

Answer 1

this one requires one more step first
\[\log(A)+\log(B)=\log(AB)\] so the first step is to write
\[\log_{18}(x(x-1))=1\]

Answer 2

then convert to exponential form, and finally solve for \(x\)
you will have to solve a quadratic equation
do you know how to do that?

Answer 3

I don't think so

Answer 4

For that question, you need the log rules. You should know that
logx+logy=logxy.
So, you get \[\log_{18}(x(x-3))=\log_{18}(x²-3x)\]
Now, if you remember how log works:
\[\log_{a}(b)=c \] can be transfer in:
\[a^c=b\]

So, can you manage from now on?
