There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 3{\frac{1}{e}}^{2} + 9{x}^{2} + 6e^{x}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{3}{e^{2}} + 9x^{2} + 6e^{x}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{3}{e^{2}} + 9x^{2} + 6e^{x}\right)}{dx}\\=&\frac{3*-2*0}{e^{3}} + 9*2x + 6e^{x}\\=&18x + 6e^{x}\\ \end{split}\end{equation} \]
