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