hello i would like to define a function, that gives me back the nth root (symbolic) of a given 4thorder equation; i want the result as a list of only expressions and not with that "x->" there is for sure no problem in solving the equation; i did it already outside the function; outside the function i also could transform the solutions into a normal list by using x/.%, but inside that wont work ... i would be very thankful if somebody could help me philipp
