To solve the equation \( e^{x+1}=\frac{1}{e} \), we start by rewriting the right side using a power of the same base. We know that \( \frac{1}{e} = e^{-1} \). Now we have: \[ e^{x+1} = e^{-1} \] Since the bases are the same, we can equate the exponents: \[ x + 1 = -1 \] Now, isolate \( x \) by subtracting 1 from both sides: \[ x = -1 - 1 \] \[ x = -2 \] Therefore, the solution set is \( \{-2\} \).
