There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ e^{5xx + 7x + 9}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = e^{5x^{2} + 7x + 9}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( e^{5x^{2} + 7x + 9}\right)}{dx}\\=&e^{5x^{2} + 7x + 9}(5*2x + 7 + 0)\\=&10xe^{5x^{2} + 7x + 9} + 7e^{5x^{2} + 7x + 9}\\ \end{split}\end{equation} \]
