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