Using the property that $a^{-n}=\frac{1}{a^n}$ for any nonzero number $a$ and positive integer $n$, we can rewrite $e^{-3}$ in the denominator as $\frac{1}{e^3}$. Then using the property that $\frac{a^m}{a^n}=a^{m-n}$ for any nonzero number $a$ and positive integers $m$ and $n$ with $m>n$, we can simplify the expression as $11eb0d3b\_9765\_938e\_9790\_dfd712fb9520\_TB1243\_11$.
