Use logarithmic differentiation to find the derivative of the following function: V6x3 + 4x(In(3x)) f (a ) = ex (x - 3) A f'(x) = 13x 9x-+2 V613 +4x(In(3x)) 6x3 +4x + rln(5x) -1 - -X er (x-5) B f'(z) = 13x 91-+2 V613 +4r(In(3x)) 623 +4r + 1 rln(31) 3 x er (x-3) Cf(x) = 13x 9r-+2 + 1 613 +4r rln(31) X V613 +4r(In(21)) er (x-2) D f' (2) = 12x 91-+2 613 +5r + 1 Iln(31) X 613 +4x(In(3x)) er (x-4)
