1. The problem statement, all variables and given/known data lim as x tends to -∞ (x)^3/5 - (x)^1/5 2. Relevant equations 3. The attempt at a solution The first thing I did was convert it into a radical so it becomes fifthroot√x^3 - fifthroot√x. Then I rationalized to get ( x^3-x)/(fifthrt√x^3+fifthroot√x) . I then divided the top by x^3 and the bottom by x^3 and x. And the final answer I got was -1/2 . Im pretty sure I did something wrong so please let me know if my answer is right or wrong.
