Simplify the square root. Assume all variables represent positive numbers. If the square root is already simplified, so state. \( \sqrt{24} \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. \( \sqrt{24}=\square \) (Type an exact answer, using radicals as needed.) B. The expression is already simplified.

To simplify \( \sqrt{24} \), follow these steps: 1. **Factor the Number Inside the Square Root:** \[ 24 = 4 \times 6 \] 2. **Identify the Largest Perfect Square Factor:** \[ 4 \text{ is a perfect square since } \sqrt{4} = 2. \] 3. **Simplify the Square Root:** \[ \sqrt{24} = \sqrt{4 \times 6} = \sqrt{4} \times \sqrt{6} = 2\sqrt{6} \] Since \( 2\sqrt{6} \) is the simplest form, the correct choice is: **A. \( \sqrt{24} = 2\sqrt{6} \)**
