There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ \frac{3{e}^{x}}{x}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{3{e}^{x}}{x}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{3{e}^{x}}{x}\right)}{dx}\\=&\frac{3*-{e}^{x}}{x^{2}} + \frac{3({e}^{x}((1)ln(e) + \frac{(x)(0)}{(e)}))}{x}\\=&\frac{-3{e}^{x}}{x^{2}} + \frac{3{e}^{x}}{x}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{-3{e}^{x}}{x^{2}} + \frac{3{e}^{x}}{x}\right)}{dx}\\=&\frac{-3*-2{e}^{x}}{x^{3}} - \frac{3({e}^{x}((1)ln(e) + \frac{(x)(0)}{(e)}))}{x^{2}} + \frac{3*-{e}^{x}}{x^{2}} + \frac{3({e}^{x}((1)ln(e) + \frac{(x)(0)}{(e)}))}{x}\\=&\frac{6{e}^{x}}{x^{3}} - \frac{6{e}^{x}}{x^{2}} + \frac{3{e}^{x}}{x}\\ \end{split}\end{equation} \]
