Best ResponseYou've already chosen the best response.0Using the distributive property\[7\sqrt{2}\left( 5\sqrt{6}4\sqrt{2} \right)\]\[=35\sqrt{12}  28\sqrt{4}\]Does this help?

Best ResponseYou've already chosen the best response.0You're multiplying \(7\sqrt{2}\) by \(4\sqrt{2}\). You multiply the coefficients together and the radicals together to give \(28\sqrt{4}\) which, of course, can be simplified.
