SV 3: Unit H Concept 7: Finding logs given approximations



The trickiest concept to learn in this problem would be remembering to add in the extra clues to your list. Remember, logb(b)=1, so we can always use that when solving for the log. Another thing you have to watch out for is expanding the logs correctly. If the log has an exponent, you have to bring it to the front of the term and turn it into a coefficient, therefore getting rid of the exponent and being able to substitute the variables in correctly later on. This will ensure that your final answer with the variables is correct.
