Best ResponseYou've already chosen the best response.1That's if you enter it in your calculator. \[4\sqrt{21}\]is the radical form of it. Also, 18.3 is rounded, so it's less accurate

Best ResponseYou've already chosen the best response.1Alright. So we want to divide the number by a perfect square,right? Like when \[\sqrt{18}=\sqrt{9\times2}\]

Grazes

Best ResponseYou've already chosen the best response.1We know that\[\sqrt{9}=3 \]so the equation turns into \[3\sqrt{2}\], leaving the 2 because it's not a perfect square and it cannot be divided more times to make a perfect square
