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


                                    This video shows you how to find a log with given clues, so it is like a treasure hunt. You use the given clues to add them or subtract them to one another using the product and quotient laws as well as the exponential law. You must also be sure to know the log property that shows that a log base (b) and the number (b) will equal one and use this clue besides the other clues given to solve the treasure hunt. This could be similar to finding the factors of your "treasure"(the log you want to find) but instead of coming up with random factors you use the ones given in the clues.
                                     Remember that when you use a clue more than once you use the exponent law to put the exponent number in front of the clue you used more than once when writing out your solution. Also, remember how to use the property log shown above properly. To illustrate, when you have log base (7) 7 you know that equals 1. However when you are solving the log you need to find you use the number 7 one of the possible factors, you do not use the number one.
