When doing the distance formula exercises, I get mixed results on what answers are required. For sqrt(178), when I simplified to 4(sqrt(11)), I was told I was wrong. Next, when doing sqrt(232), I kept it thinking that's what it wanted. Turns out 2(sqrt(58)) was needed. Can this be resolved to one format?
