**Hey everyone, someone please dive in here and help me. I have tried for over an hour now to figure out how to enter an index over 3 into my radical problems. For instance, how do I enter this into my TI-83? I have a test monday, I am trying to study and I am stuck on this, driving me nutz. I know she went over it in class, I dont remember how to enter it.** Okay, how do I enter that, the "5" I cannot for the life of me remember how to do it, and Im not gettng anywhere online. All the google is saying, is to Hit Math, then number 5 for the x index, but it is not taking my 5 ? help please, Im so behind now
