There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ m{({x}^{4} + 3)}^{(\frac{-1}{r})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = m(x^{4} + 3)^{(\frac{-1}{r})}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( m(x^{4} + 3)^{(\frac{-1}{r})}\right)}{dx}\\=&m((x^{4} + 3)^{(\frac{-1}{r})}((0)ln(x^{4} + 3) + \frac{(\frac{-1}{r})(4x^{3} + 0)}{(x^{4} + 3)}))\\=&\frac{-4mx^{3}(x^{4} + 3)^{(\frac{-1}{r})}}{(x^{4} + 3)r}\\ \end{split}\end{equation} \]
