    HELLO

    First, isolate for the term in x :

    \ln{(x)} + 3 \ln{(2)} + 1 = 0

    \ln{(x)} = - 3 \ln{(2)} - 1

    Now exponentiate with base e :

    x = e^{- 3 \ln{(2)} - 1}

    This is approximatively equal to :

    x \approx 0.046

    And can be written as a fraction as follows :

    x = \frac{1}{8e}

    THANK YOU FOR YOUR QUESTION
