when the elevator at Franklin’s apartment building went out of service, Franklin walked up 15 flights of stairs. He stopped to rest after every 3 flights. How many times did Franklin stop to rest?

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
