1. The problem is to simplify or understand the expression $\sqrt{x}299$. 2. The square root symbol $\sqrt{x}$ means the principal square root of $x$, which is the number that when squared gives $x$. 3. The expression $\sqrt{x}299$ can be interpreted as $299 \times \sqrt{x}$, since there is no operator between $\sqrt{x}$ and $299$. 4. Therefore, the expression is simply $299\sqrt{x}$. 5. If you want to evaluate this expression for a specific value of $x$, substitute that value into $\sqrt{x}$ and multiply by 299. 6. For example, if $x=4$, then $\sqrt{4}=2$, so the expression equals $299 \times 2 = 598$. 7. Without a specific value for $x$, the simplified form is $299\sqrt{x}$.
