There are 1 questions in this calculation: for each question, the 4 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ ln(ln(x))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( ln(ln(x))\right)}{dx}\\=&\frac{1}{(ln(x))(x)}\\=&\frac{1}{xln(x)}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{1}{xln(x)}\right)}{dx}\\=&\frac{-1}{x^{2}ln(x)} + \frac{-1}{xln^{2}(x)(x)}\\=&\frac{-1}{x^{2}ln(x)} - \frac{1}{x^{2}ln^{2}(x)}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( \frac{-1}{x^{2}ln(x)} - \frac{1}{x^{2}ln^{2}(x)}\right)}{dx}\\=&\frac{--2}{x^{3}ln(x)} - \frac{-1}{x^{2}ln^{2}(x)(x)} - \frac{-2}{x^{3}ln^{2}(x)} - \frac{-2}{x^{2}ln^{3}(x)(x)}\\=&\frac{2}{x^{3}ln(x)} + \frac{3}{x^{3}ln^{2}(x)} + \frac{2}{x^{3}ln^{3}(x)}\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( \frac{2}{x^{3}ln(x)} + \frac{3}{x^{3}ln^{2}(x)} + \frac{2}{x^{3}ln^{3}(x)}\right)}{dx}\\=&\frac{2*-3}{x^{4}ln(x)} + \frac{2*-1}{x^{3}ln^{2}(x)(x)} + \frac{3*-3}{x^{4}ln^{2}(x)} + \frac{3*-2}{x^{3}ln^{3}(x)(x)} + \frac{2*-3}{x^{4}ln^{3}(x)} + \frac{2*-3}{x^{3}ln^{4}(x)(x)}\\=&\frac{-6}{x^{4}ln(x)} - \frac{11}{x^{4}ln^{2}(x)} - \frac{12}{x^{4}ln^{3}(x)} - \frac{6}{x^{4}ln^{4}(x)}\\ \end{split}\end{equation} \]
