Subtract, then divide/simplify. \[2\sqrt{2}\]

Answer 4

√(16-8) signifies what you're asking.

Answer 5

\[\sqrt{16-8} = \sqrt{8} = \sqrt{2*2*2} = \sqrt{2*2} * \sqrt{2} = 2*\sqrt{2}=2\sqrt{2}\]

For every pair of identical factors under the square root sign, you can replace the pair with 1 outside of the square root sign, as I did here with 2*2
