Somebody help me with this?

Answer:
from top to bottom: [tex]6\sqrt{2}, 2\sqrt{6} , 5\sqrt{2}, 2\sqrt{5}[/tex]
Step-by-step explanation:
[tex]1) 6\sqrt{2} = \sqrt{36} * \sqrt{2} = \sqrt{72} \\2) 2\sqrt{6} = \sqrt{4} * \sqrt{6} = \sqrt{24} \\3) 5\sqrt{2} = \sqrt{25} * \sqrt{2} = \sqrt{50}\\4) 2\sqrt{5} = \sqrt{4} * \sqrt{5} = \sqrt{20}[/tex]
