There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 900.5{e}^{0.222}x\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 900.5xe^{\frac{111}{500}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 900.5xe^{\frac{111}{500}}\right)}{dx}\\=&900.5e^{\frac{111}{500}} + \frac{900.5x*0.222*0}{e^{\frac{389}{500}}}\\=&900.5e^{\frac{111}{500}}\\ \end{split}\end{equation} \]
