Question
![### Transcription and Explanation
This mathematical solution involves solving an equation for a variable, denoted as \( u \), by using an exponential expression. Below is a transcription and explanation.
#### Given Equation:
\[
1.10 = 45 \left[ 1 (e^t)^{-0.33333} \right] - 15 \left[ 1 - 1 (e^t)^{-0.33333} \right]^{0.66666}
\]
#### Steps:
1. **Substitution:**
- Let \( e^t = u \).
2. **Rewriting the Equation:**
- Substitute \( u \) into the equation to get:
\[
1.10 = 45 \left[ u^{-0.33333} \right] - 15 \left[ 1 - u^{-0.33333} \right]^{0.66666}
\]
3. **Goal:**
- Find the value of \( u \).
4. **Solution Box:**
- The solution gives:
\[
u = 2158.54545
\]
- Calculating \( t \) using the natural logarithm function:
\[
t = \ln(2158.54545)
\]
- Resulting in:
\[
t = 7.627
\]
This transcription provides the step-by-step transformation and illustration of the calculus involved in finding \( u \) and further calculations to evaluate \( t \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F02152486-4b3e-4971-933f-7bbbd61f61b8%2F469716d1-19b7-43b7-bde1-4697d798e615%2Fj4m1jm_processed.jpeg&w=3840&q=75)
