    Solve: 2 ln 3 = ln (x - 4)

    a) x = 9

    b) x = 10

    c) x = 13

    Answer:

    x = 13

    Step-by-step explanation:

    To solve the problem above, we will follow the steps below;

    2 ln 3 = ln (x - 4)

    [using logarithm rule aInb = Inbᵃ]

    so also our equation becomes

    In 3² = In (x-4)

    The In at the left-hand side of the equation will cancel-out the In at the right-hand side of the equation

    Our equation becomes;

    3² = x - 4

    9 = x-4

    add 4 to both-side of the equation in other to make x subject of the equation

    9 + 4 = x-4 + 4

    13 = x

    x = 13
