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