There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 3ln(x - 3) - ln(x - 1)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3ln(x - 3) - ln(x - 1)\right)}{dx}\\=&\frac{3(1 + 0)}{(x - 3)} - \frac{(1 + 0)}{(x - 1)}\\=&\frac{3}{(x - 3)} - \frac{1}{(x - 1)}\\ \end{split}\end{equation} \]
