= Optimization =

If you want to take the second or third root of a number, use [[TI-BASIC:Square_Root|√(]] or [[TI-BASIC:Cube_Root|³√(]] instead.

:2×√X
can be
:√(X

= Error Conditions =

* '''[[TI-BASIC:Errors#N|ERR:NONREAL ANS]]''' if you try to take an even root of a negative number or list element in Real mode.
