There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 0.13x(ln(20.13) - ln(x))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.13xln(20.13) - 0.13xln(x)\right)}{dx}\\=&0.13ln(20.13) + \frac{0.13x*0}{(20.13)} - 0.13ln(x) - \frac{0.13x}{(x)}\\=&0.13ln(20.13) - 0.13ln(x) - 0.13\\ \end{split}\end{equation} \]
