I don't completely believe that they would give you this type of questions. But if they do, I am pretty sure they would only give easy numbers to calculate. Like the Log of 100 which is 2, 10 is 1 and so on. Those are just easy and quick to recall. YOu dont even need a calculator to solve the log of 100 and 10. Focus more on dosage calculation of all types, doses, tpn, kcal, meq, milliosmoles, compounding, ratio and proportion, %, and so on. In my exam I was able to use the square root function of the calculator. Goodluck!
