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