1. The problem is to simplify or understand the expression $3\sqrt{x}$. 2. The notation $3\sqrt{x}$ typically means $3 \times \sqrt{x}$, which is three times the square root of $x$. 3. If you want to express it differently, you can write it as $$3\sqrt{x} = 3x^{\frac{1}{2}}.$$ 4. This means you multiply 3 by $x$ raised to the power of one-half, which is the same as the square root of $x$. 5. This is the simplified form unless additional information about $x$ is given or if you need to evaluate for specific values of $x$.
