Find two consecutive whole numbers that
square root 30 lies between.

The sqrt(30) is between the sqrt(25)=5 and sqrt(36)=6. The two consecutive whole numbers around sqrt(30) are 5 and 6

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
