To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc. it gives the cube the 4th power, 5th, 6th, etc. If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on. When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.
The syntax of the command is value [Y to x] (1/ order of root)
Ex: cube root of 27 is entered as 27 [Y to x] (1/3)
