Hi, Jacob.
If you are simply stating the answer, you will write it as an
equation, using the radical symbol merely as a notation that says you
are taking the square root:
___
\/ 9 = 3
There is one way to calculate a root in which you treat the radical
sign as a device for calculating similar to the long division
notation:
__3__4_
\/ 11 56
9
--
6?*? 2 56
64*4 = 2 56
----
0
Here you write the answer above, with one digit over each pair of
digits in the "radicand." But you only do this when you are using this
method.
You can read about this method in the Dr. Math archives:
