Find ds/dt.
![The equation provided is:
\[ s = \frac{2t^4 - 3t}{t^3} \]
The task is to find the derivative \(\frac{ds}{dt}\).
### Explanation:
This problem involves finding the derivative of a function \(s\) with respect to \(t\). The expression given is a fraction where the numerator is \(2t^4 - 3t\) and the denominator is \(t^3\).
### Steps to Solve:
1. **Simplify the Expression**:
- Divide each term in the numerator by \(t^3\):
- \(\frac{2t^4}{t^3} = 2t\)
- \(\frac{-3t}{t^3} = -\frac{3}{t^2}\)
- This simplifies the expression to:
\[ s = 2t - \frac{3}{t^2} \]
2. **Differentiate the Simplified Expression**:
- Use the power rule \(\frac{d}{dt}[t^n] = nt^{n-1}\) to find \(\frac{ds}{dt}\):
- The derivative of \(2t\) is 2.
- The derivative of \(-\frac{3}{t^2}\) is:
- Rewrite as \(-3t^{-2}\)
- Using the power rule: \(-3(-2)t^{-3} = 6t^{-3}\)
3. **Final Result**:
- Combine the derivatives:
\[\frac{ds}{dt} = 2 + \frac{6}{t^3}\]
Hence, the derivative \(\frac{ds}{dt}\) is \(2 + \frac{6}{t^3}\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faf0ca71f-1e06-4606-8323-27f11451a430%2F6c135228-0c4b-45f9-bbcb-9224417174ca%2Fuehic5_processed.jpeg&w=3840&q=75)
