The radical symbol is used to calculate square roots. It a radical has a small 3 to the top left of it, it means cubic root. It it has a a small n or a small x to the top left of it, it means nth root.
The way any of these roots works is one of the following:
Enter a number (positive for a square root or an nth root with n even) then press the square root button. The result is then displayed.
The other way is to press the root key then enter the number whose root you wan t calculate. The result is then displayed.
If you press the square root key and a radical is displayed withy a left parenthesis, you can be sure it is the second way.
SOURCE: how do I change from a radical to a decimal for a
Hello,
There is a key that shows 2 white arrows, one to the left, the other to the right. You use it to convert from fractions to decimals, and from radicals to decimal. Key is used to toggle between display formats.
Hope it helps.
