    Use the change of base property and make a simple substitution.

    Nope, I mean you use \log_{10}x=\frac{\ln x}{\ln10}

    The denominator is a constant and you only have to integrate \frac{\ln x}x

    You mean for example \frac{\dfrac ab}c?

    It's the same if we write \frac ab:c, then you make a cross product.

    If we have

    x=\frac{\dfrac ab}c=\frac a{bc}

    but be careful, if we have

    x=\frac a{\dfrac bc}=\frac{ac}b

    It depends.
