    Condensing Logarithms

    I need to condense the following logarithm:
    4[ln(x)  ln(x + 5)  ln(x  5)]

    Is this one supposed to be a trick question?

    Hmm, it appears there are minus signs in there? Does the corrected LaTeX show a true representation of the question?

    ln(x)-ln(x-5)-ln(x-5) = ln(x) - [ln(x-5)+ln(x+5)]

    ln({\frac{x}{x^2-25}})
