There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{300}{(3 + 17{e}^{(\frac{-1}{5}t)})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{300}{(17{e}^{(\frac{-1}{5}t)} + 3)}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{300}{(17{e}^{(\frac{-1}{5}t)} + 3)}\right)}{dx}\\=&300(\frac{-(17({e}^{(\frac{-1}{5}t)}((0)ln(e) + \frac{(\frac{-1}{5}t)(0)}{(e)})) + 0)}{(17{e}^{(\frac{-1}{5}t)} + 3)^{2}})\\=&0\\ \end{split}\end{equation} \]
