A, B, and C are clearly rational numbers

In D, if you had somehow showed that the decimals do not end and do not
continue in some obvious pattern, then I could tell
It is also rational the way you showed it.

e.g. 1.73205080757.... I would classify as irrational
i mean
A.√3
and
D.√9
oh so is D classified as a irrational number bc of its pattern?
