1. The problem statement, all variables and given/known data https://i.imgur.com/U8muIJS.jpg 2. Relevant equations Not aware of any equations required. 3. The attempt at a solution For these questions I don't understand what I'm suppose to even. I have researched the terms prefix notation and Identifying calculations but after hours of researching I'm so lost. I know its says that is not acceptable but I truly do not know how to answer this question. If anyone could even just point me in the correct direction I be very grateful. I believe the prefix notation has something to do with powers of 3.
