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