There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ {X}^{(\frac{5}{3})} - {X}^{(\frac{2}{3})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( {X}^{\frac{5}{3}} - {X}^{\frac{2}{3}}\right)}{dx}\\=&({X}^{\frac{5}{3}}((0)ln(X) + \frac{(\frac{5}{3})(0)}{(X)})) - ({X}^{\frac{2}{3}}((0)ln(X) + \frac{(\frac{2}{3})(0)}{(X)}))\\=& - \frac{0}{3}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( - \frac{0}{3}\right)}{dx}\\=& - 0\\ \end{split}\end{equation} \]
