Heads up: If the answer is a terminating or repeating number, it is not an irrational number, so cross those out

love_ranaa · Answer

So we can see right now that D and A are crossed out

Would it be B?

The square root of 100 is 10 divided by 3 is 3.3 (repeating)
The square root of 8 is 2.842

So what do you think?
