Let $g(x)=\int_{4}^{x}(5+\sqrt{t}) d t$. Find $g^{\prime}(x)$.
\[
g^{\prime}(x)=
\]
Therefore, the final answer is \(\boxed{g^{\prime}(x)=5+\sqrt{x}}\).
Step 1 :Let $g(x)=\int_{4}^{x}(5+\sqrt{t}) d t$.
Step 2 :By the Fundamental Theorem of Calculus, the derivative of the integral of a function from a constant to x is just the function evaluated at x.
Step 3 :So, $g^{\prime}(x)=5+\sqrt{x}$.
Step 4 :Therefore, the final answer is \(\boxed{g^{\prime}(x)=5+\sqrt{x}}\).
