Answered by help!!!!!!!!!!!!!!!!!!!!!!!!!!!!
it has to be one of them its a multiple choice. and they have a sign above them the looks like a v with a line above it _
Answered by Reiny
ahhh, so they are square roots
clearly √16, √100, and √81 are all whole numbers, thus rational
but √11 = appr 3.31662479...
never ends, never repeats , so IRRATIONAL (not rational, not a ratio, not a fraction)
