There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 9{t}^{(\frac{{t}^{1}}{2})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 9{t}^{(\frac{1}{2}t)}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 9{t}^{(\frac{1}{2}t)}\right)}{dx}\\=&9({t}^{(\frac{1}{2}t)}((0)ln(t) + \frac{(\frac{1}{2}t)(0)}{(t)}))\\=&\frac{0}{2}\\ \end{split}\end{equation} \]
