### How do you do you put square roots into its simplest radical form? Because I can do small numbers mentally but when they are bigger I get stuck..

well,

I really don't like to tell this to you but the Ti-84 plus will not display a square root as an answer, it will always return answers in decimal form. The best way for you to simplify roots is by using a factor tree and knowing your squares up to 30. I went through all of that using a ti-83 plus so I completely understand your desire for it to show a root, it just won't. I really wish you the best with this problem, but having read the owners manual for it, I just don't see any other way to do it.

The first sequence takes the square root of 87.34/5, the second sequence calculates 87.34/5 then takes the square root of the result.
