WebLearn easy way to solve log of a quotient/fraction Quotient rule of logarithm function#shorts #maths #MathsSoSimple WebIf you meant: f (x) = log₃ [ (4x-3)²] Then the domain is x≠ ¾ because that value would lead to a log of 0. The square makes sure we never get a negative value for the argument. If you mean f (x) = {log₃ [ (4x-3)}² which is usually written as log²₃ (4x-3) then: As before x≠ ¾ due to being a log of 0. huffy roadcreek all terrain
