4 squre root 81


Take the fourth root. The square root, denoted by a 2 on top of the "root thing" or more commonly without a number at all, is the second root.

Usually the easiest way to calculate the fourth root is to calculate the square root of the square root. So in this case the fourth root of 81 is the square root of the square root of 81. The square root of 81 is 9, the square root of 9 is 3.

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.
