There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 8.33ln(x + 8.53) - 13.85\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 8.33ln(x + 8.53) - 13.85\right)}{dx}\\=&\frac{8.33(1 + 0)}{(x + 8.53)} + 0\\=&\frac{8.33}{(x + 8.53)}\\ \end{split}\end{equation} \]
