There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ ({t}^{5} + {t}^{2} - 3t)ln(8t)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = t^{5}ln(8t) + t^{2}ln(8t) - 3tln(8t)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( t^{5}ln(8t) + t^{2}ln(8t) - 3tln(8t)\right)}{dx}\\=&\frac{t^{5}*0}{(8t)} + \frac{t^{2}*0}{(8t)} - \frac{3t*0}{(8t)}\\=& - \frac{0}{8}\\ \end{split}\end{equation} \]
