There are 1 questions in this calculation: for each question, the 4 derivative of e is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ ln(e)\ with\ respect\ to\ e：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( ln(e)\right)}{de}\\=&\frac{1}{(e)}\\=&\frac{1}{e}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{1}{e}\right)}{de}\\=&\frac{-1}{e^{2}}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( \frac{-1}{e^{2}}\right)}{de}\\=&\frac{--2}{e^{3}}\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( \frac{2}{e^{3}}\right)}{de}\\=&\frac{2*-3}{e^{4}}\\=&\frac{-6}{e^{4}}\\ \end{split}\end{equation} \]
