an attachment is the best way to give you first fundamental informations. Please take a look: In the left column of the table there are the rules how to calculate power values; in the right column there are the corresponding rules how to calculate logarithm values.
(I am very much in a hurry. I hope that I'll find some time this afternoon to give you more detailed informations. But maybe the attachment helps a little bit further with your studies.)
