There are 1 questions in this calculation: for each question, the 5 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 5th\ derivative\ of\ function\ \frac{({x}^{2} + 2x)}{e^{x}}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{x^{2}}{e^{x}} + \frac{2x}{e^{x}}\\\\ &\color{blue}{The\ 5th\ derivative\ of\ function:} \\=&\frac{-10}{e^{x}} + \frac{8x}{e^{x}} - \frac{x^{2}}{e^{x}}\\ \end{split}\end{equation} \]
