1. The problem is to simplify the expression \( \sqrt{x}625 \).\n2. First, clarify the expression: it likely means \( \sqrt{x} \times 625 \) or \( 625 \sqrt{x} \).\n3. The square root function is defined as \( \sqrt{x} = x^{\frac{1}{2}} \).\n4. So, the expression can be written as \( 625 \times x^{\frac{1}{2}} \).\n5. This is the simplified form unless more information about \( x \) is given.\n6. If you want to express it as a single term, it is \( 625x^{\frac{1}{2}} \).
