There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ {ln(x)}^{3}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = ln^{3}(x)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( ln^{3}(x)\right)}{dx}\\=&\frac{3ln^{2}(x)}{(x)}\\=&\frac{3ln^{2}(x)}{x}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{3ln^{2}(x)}{x}\right)}{dx}\\=&\frac{3*-ln^{2}(x)}{x^{2}} + \frac{3*2ln(x)}{x(x)}\\=&\frac{-3ln^{2}(x)}{x^{2}} + \frac{6ln(x)}{x^{2}}\\ \end{split}\end{equation} \]
