That'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

Do you know how to simplify it so that it turns into the radical form?

Alright. So we want to divide the number by a perfect square,right?
Like when \[\sqrt{18}=\sqrt{9\times2}\]
Grazes
Best Response

1
We 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
