sir example five on what we did today , how did you get the final answer? .. 1 over 2187 ??
The final answer as you see using the simple method is 1/27.
Using the more formal method I stopped half way through that question because I will have to teach you how to use logs and I didn't think we had time to get into it at the end of class. So I will finish this tomorrow. Sorry about the confusion.
