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