The first derivative of ln x is 1/x, which (for the following) you better write as x-1.

Now use the power rule:

Second derivative (the derivative of the first derivative) is -1x-2, the third derivative is the derivative of this, or 2x-3. You may now wish to write this in the alternative form, as 2 / x3.
