There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 3.81{x}^{3}ln(x) + 3.67{x}^{3}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3.81x^{3}ln(x) + 3.67x^{3}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3.81x^{3}ln(x) + 3.67x^{3}\right)}{dx}\\=&3.81*3x^{2}ln(x) + \frac{3.81x^{3}}{(x)} + 3.67*3x^{2}\\=&11.43x^{2}ln(x) + 3.81x^{2} + 11.01x^{2}\\ \end{split}\end{equation} \]
