Best ResponseYou've already chosen the best response.0Not really, the reason for why you take out the i is that you want the minus under the squareroot to disappear

Best ResponseYou've already chosen the best response.0So based on the definition of \[i=\sqrt{1}\] what's, for example \[\sqrt{7}\]

Best ResponseYou've already chosen the best response.0\[i \sqrt{10}(11+i \sqrt{5})\]=\[11i \sqrt{10}+i ^{2}\sqrt{10}\sqrt{5}= 11i \sqrt{10}\sqrt{50}\]
