1. The problem is to understand why the expression is written as $8e^1$. 2. The expression $8e^1$ means $8$ multiplied by $e$ raised to the power of $1$. 3. Recall that any number raised to the power of $1$ is the number itself, so $e^1 = e$. 4. Therefore, $8e^1 = 8 \times e$. 5. This is a way to write $8$ times the mathematical constant $e$ (approximately 2.718). 6. So, $8e^1$ is just a concise way to write $8e$.
