The simplified form of $\sqrt{x}$ is $\sqrt{x}$.

This expression cannot be simplified further unless you know the value of $x$. If $x$ is a perfect square (like 4, 9, 16, etc.), then $\sqrt{x}$ can be simplified to an integer. For instance:

• If $x = 4$, then $\sqrt{4} = 2$.
• If $x = 9$, then $\sqrt{9} = 3$.

If $x$ is not a perfect square, the expression $\sqrt{x}$ is already in its simplest form.

Tip: When dealing with square roots, always check if the number under the root is a perfect square to simplify it further.
