There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 8x{\frac{1}{(x - 5)}}^{7}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{8x}{(x - 5)^{7}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{8x}{(x - 5)^{7}}\right)}{dx}\\=&8(\frac{-7(1 + 0)}{(x - 5)^{8}})x + \frac{8}{(x - 5)^{7}}\\=&\frac{-56x}{(x - 5)^{8}} + \frac{8}{(x - 5)^{7}}\\ \end{split}\end{equation} \]
