I need help with square root functions


Hello,
The square root has a dedicated key sequence [2nd][V square root symbol]
Square root of 21.2846 is entered [2nd][V square root] 21.2846 [ENTER] .
The result is`4.614.
I suspect you want to calculate the 4th root of 21.2846. If it is the case you enter that as
21.2846 [^](1/4) =2.148
Square root can be also entered as [^](1/2)
Cube root is entered as [^] (1/3)

..
nth root is entered as [^](1/n)
Hope it helps.
