State whether the following statements are true or false:
(i) 1 { 1,2,3}
(ii) a ⊂ {b,c,a}
(iii) {a} {a,b,c}
(iv) {a,b} = {a,a,b,b,a}
(v) The set {x:x + 8 = 8} is the null set.
(i) True
1 belongs to the given set as it is present in it.
(ii) False
{a} ⊂ {b,c,a}
This is the write form to write it or a ϵ {b,c,a}
(iii) False
{a} ⊂ {b,c,a}
This is the write form to write it or a ϵ {b,c,a}
(iv) True
We do not repeat same elements in a given set.
∴ The given set can be written as {a,b}
(v) False
X+8 = 8
i.e. x = 0
{0} It is not a null set
