There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (x + 3){x}^{\frac{1}{2}}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x{x}^{\frac{1}{2}} + 3{x}^{\frac{1}{2}}\right)}{dx}\\=&{x}^{\frac{1}{2}} + x({x}^{\frac{1}{2}}((0)ln(x) + \frac{(\frac{1}{2})(1)}{(x)})) + 3({x}^{\frac{1}{2}}((0)ln(x) + \frac{(\frac{1}{2})(1)}{(x)}))\\=&\frac{3x^{\frac{1}{2}}}{2} + \frac{3}{2x^{\frac{1}{2}}}\\ \end{split}\end{equation} \]
