There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (16x - 20)ln(4x - 5)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 16xln(4x - 5) - 20ln(4x - 5)\right)}{dx}\\=&16ln(4x - 5) + \frac{16x(4 + 0)}{(4x - 5)} - \frac{20(4 + 0)}{(4x - 5)}\\=&16ln(4x - 5) + \frac{64x}{(4x - 5)} - \frac{80}{(4x - 5)}\\ \end{split}\end{equation} \]
