There are 1 questions in this calculation: for each question, the 4 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ 0.0749x*4 - 1.6644x*3 + 9.8626x*2 - 8.0981x + 53.169\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.2996x - 4.9932x + 19.7252x - 8.0981x + 53.169\right)}{dx}\\=&0.2996 - 4.9932 + 19.7252 - 8.0981 + 0\\=&6.9335\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 6.9335\right)}{dx}\\=&0\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 0\right)}{dx}\\=&0\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( 0\right)}{dx}\\=&0\\ \end{split}\end{equation} \]
