1. The problem is to simplify or understand the expression $\sqrt{3}$. 2. The square root symbol $\sqrt{}$ means to find a number which, when multiplied by itself, gives the number inside the root. 3. Here, $\sqrt{3}$ means the number which when squared equals 3. 4. Since 3 is not a perfect square, $\sqrt{3}$ is an irrational number approximately equal to 1.732. 5. We cannot simplify $\sqrt{3}$ further into a simpler radical or integer. 6. Therefore, the simplest form of $\sqrt{3}$ is just $\sqrt{3}$ itself.
