1. looks like you expect somebody to do an assignment or homework for you, and you have not shown any work or indication where your problems lie.
What don' t you understand about these questions.
They all seem to deal with "geometric mean"

btw, you will have more luck posting individual problems, showing some steps or work on your part.
