Which expression represents the circumference of the smaller circle with radius OA?

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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:
