The viewer needs to pay special attention to the approximations that he/she would use and the ones on the video. There are several ways to factor the logs, and the approximations, itself, can be factored (for ex. in this video: 4 and 2). Remember that when expanding logs: multiplication corresponds to addition; division corresponds with subtraction; and exponents move to the front of the log and act like coefficients. And finally, one must know and remember that logbb=1 and logb1=0, which serves as two extra approximations.
