To rewrite the expression \( \ln 7 + 3 \ln w - 2 \ln x \) using the properties of logarithms, we can apply the Product Rule, Quotient Rule, and Power Rule as follows:

  1. Power Rule: Rewrite \( 3 \ln w \) as \( \ln w^3 \) and \( -2 \ln x \) as \( \ln x^{-2} \).

    \[ \ln 7 + \ln w^3 + \ln x^{-2} \]

  2. Product Rule: Combine \( \ln 7 \) and \( \ln w^3 \):

    \[ \ln (7 w^3) \]

  3. Quotient Rule: Now include \( \ln x^{-2} \):

    \[ \ln \left( \frac{7 w^3}{x^2} \right) \]

So, the final expression is:

\[ \ln \left( \frac{7 w^3}{x^2} \right) \]

Among the given options, this expression matches with:

ln(7w³/x²), which corresponds to "the natural log of open paren the fraction with numerator 7 w cubed and denominator x squared close paren."

Thus, the correct choice is:

ln(7w³/x²).
