To rewrite the expression \( \frac{5}{s^{-7}} \) with a positive exponent, you can use the property of exponents that states \( s^{-n} = \frac{1}{s^n} \).
Here’s how it works:
- Rewrite the expression: \[ \frac{5}{s^{-7}} = 5 \cdot s^{7} \quad \text{(because dividing by } s^{-7} \text{ is the same as multiplying by } s^{7}) \]
Thus, the expression with a positive exponent is: \[ 5s^{7} \]
