    When I was studying for PPD I ran into this equation in Ballast as well.  I skipped over it and was happy I did.  In my opinion, I would focus more on understanding the questions the exam provides you.  This extraneous information is good to have a general understanding of but if I were a betting man I couldn't imagine them asking you to any equations that would require memorizing this formula.
