The correct Answer is:
To find the square root of \( \sqrt{32} - \sqrt{24} \), we can follow these steps: ### Step 1: Simplify the square roots First, we simplify \( \sqrt{32} \) and \( \sqrt{24} \). \[ \sqrt{32} = \sqrt{16 \times 2} = \sqrt{16} \cdot \sqrt{2} = 4\sqrt{2} \] \[ \sqrt{24} = \sqrt{4 \times 6} = \sqrt{4} \cdot \sqrt{6} = 2\sqrt{6} \] ### Step 2: Substitute back into the expression Now we substitute these simplified forms back into the expression: \[ \sqrt{32} - \sqrt{24} = 4\sqrt{2} - 2\sqrt{6} \] ### Step 3: Factor out the common term Next, we can factor out a common term from the expression: \[ = 2(2\sqrt{2} - \sqrt{6}) \] ### Step 4: Find the square root of the expression Now we need to find the square root of \( 2(2\sqrt{2} - \sqrt{6}) \): \[ \sqrt{2(2\sqrt{2} - \sqrt{6})} = \sqrt{2} \cdot \sqrt{2\sqrt{2} - \sqrt{6}} \] ### Step 5: Simplify further if possible To simplify \( \sqrt{2\sqrt{2} - \sqrt{6}} \), we can express it in a different way: Let \( x = \sqrt{2\sqrt{2} - \sqrt{6}} \). To simplify, we can try to express \( 2\sqrt{2} - \sqrt{6} \) in a form that can be squared. ### Step 6: Rationalizing or completing the square We can try to express \( 2\sqrt{2} - \sqrt{6} \) in terms of a perfect square. Let’s assume: \[ 2\sqrt{2} - \sqrt{6} = a - b \] Squaring both sides gives: \[ (2\sqrt{2} - \sqrt{6})^2 = a^2 - 2ab + b^2 \] This might be complex, so we can directly compute \( 2\sqrt{2} - \sqrt{6} \) and check if it can be simplified further. ### Final Result Thus, the final expression for the square root is: \[ \sqrt{2} \cdot \sqrt{2\sqrt{2} - \sqrt{6}} \]
