SV #3: Unit H Concept 7 - Finding logs when given approximations
It is important to remember that when you have a root of any kind, that root turns into an exponent as well. From that exponent, you can create a coefficient in front of your log, furthering the expansion. Also, it is good to remember that you have two hints of your own (which are not given) from our basic knowledge of logs. If you have log(base b)b, the answer, or it equates to 1. If you have log(base b)1, your answer would be 0 because anything to the 0 power is 1. It is always good to refer back to your knowledge of the exponential formula. Also, despite not being shown in this particular video, it is good to remember that at times, when our log's quantity is a fraction, we may have to multiply the numerator and denominator by a common number, because the given log may not have any factors that correspond with our hints.
