Is our test going to be on the examples in the book or random questions in our book?

Either way is usually fine. If you have a graph it's ok to write answer from observation.

hi sir, question on indices... for example 2 on this section, did you simply put all the information into the calculator to get your answer after simplifiying it out to your extent ?

I think example 2 (as in video) was done without a calculator. Will look at this question in class.
