There are 1 questions in this calculation: for each question, the 4 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ 486786x - {x}^{548}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 486786x - x^{548}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 486786x - x^{548}\right)}{dx}\\=&486786 - 548x^{547}\\=& - 548x^{547} + 486786\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( - 548x^{547} + 486786\right)}{dx}\\=& - 548*547x^{546} + 0\\=& - 299756x^{546}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( - 299756x^{546}\right)}{dx}\\=& - 299756*546x^{545}\\=& - 163666776x^{545}\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( - 163666776x^{545}\right)}{dx}\\=& - 163666776*545x^{544}\\=& - 89198392920x^{544}\\ \end{split}\end{equation} \]
