There are 1 questions in this calculation: for each question, the 4 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ (4x - 1)(4x - 1)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 16x^{2} - 8x + 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 16x^{2} - 8x + 1\right)}{dx}\\=&16*2x - 8 + 0\\=&32x - 8\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 32x - 8\right)}{dx}\\=&32 + 0\\=&32\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 32\right)}{dx}\\=&0\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( 0\right)}{dx}\\=&0\\ \end{split}\end{equation} \]
