1. Stating the problem: Simplify the expression $\sqrt{x}5$. 2. Understanding the expression: The expression $\sqrt{x}5$ means $5$ multiplied by the square root of $x$, which can be written as $5\sqrt{x}$. 3. There is no further simplification possible unless we know the value of $x$ or if $x$ is a perfect square. 4. Therefore, the simplified form of the expression is: $$5\sqrt{x}$$ This is the final answer.
