To simplify the fraction \(-\frac{3(v^3)^{-5}}{6s^{-7}}\), we can follow these steps:

  1. Rewrite the terms with negative exponents as positive exponents. Recall that \(a^{-n} = \frac{1}{a^n}\) or \(a^{-n} = \frac{1}{a^n}\).

    The expression becomes: \[ -\frac{3}{6} \cdot \frac{1}{(v^3)^5} \cdot s^7 \]

  2. Simplify the expression. Start with \(-\frac{3}{6}\): \[ -\frac{3}{6} = -\frac{1}{2} \]

    Next, simplify \((v^3)^{-5}\): \[ (v^3)^{-5} = \frac{1}{(v^3)^5} = \frac{1}{v^{15}} \] Therefore, we have: \[ -\frac{1}{2} \cdot \frac{1}{v^{15}} \cdot s^7 = -\frac{s^7}{2v^{15}} \]

  3. Thus, combining everything together, the final result is: \[ -\frac{s^7}{2v^{15}} \]

This is the simplest form of the given fraction with positive exponents.
