Solution. Let f(x) = \sqrt{x}. Then we can rewrite that as:
\begin{align*} f(x) = \sqrt{x} = x^{1/2}. \end{align*}
\begin{align*} f'(x) = \frac{1}{2}x^{-\frac{1}{2}} = \frac{1}{2\sqrt{x}}. \end{align*}
\begin{align*} f(x) = \sqrt{x} = x^{1/2}. \end{align*}
\begin{align*} f'(x) = \frac{1}{2}x^{-\frac{1}{2}} = \frac{1}{2\sqrt{x}}. \end{align*}
