Can I go any farther from here: Log(2x)? If yes, what property should I use?

    Depends on what you are doing, if you are expanding the log you could write it as: log(2) + log(x)

    I was trying to do exactly the same. I was not sure if I could do that

    then you need to take the ln of both sides.

    applying the log properties I end up with:

    Is there something else I can do now?

    specially with the term ln(2x-1)?

    The only part you need to fix is that -(ln(5x^2)) should be -(ln(5)+2ln(x))

    because in the problem only x is raised to the 2nd power and not the 5. the ln(2x-1) is in simplest form.

    So that must be the answer, right? Of course changing 2(ln5+lnx) by ln5+2lnx

    exactly (also make sure that end is in parentheses and negated as it's in the denominator)

    I suppose this is the answer
