#1 ok
#2 Since A and B are equivalent, and D is obviously false, it must be C.
#3 only C and E
Since 2 is not a perfect square, its square root must be irrational
B is not a repeating decimal. Its groups of digits keep getting longer, and it does not terminate.
#4 also B. Since you got A right, I'm surprised that you also picked B.
1^2 = 1
2^2 = 4
3^2 = 9
So 7 is not a perfect square.
#5 all except A are irrational, since only 36 is a perfect square.
