Question

does {2} belong to {{2,3},4}?
tell me why? ​

Answer 1

Hey

{2} does belong to {{2,3},4}

Because {2,3} is an element as whole and {2} or {3} can't be written independently

It may be written that {2,3}€ {{2,3},4}.

Answer 2

Answer:

{2} does not belong to {{2,3}], 4}

Step-by-step explanation:

Let A={{2,3}, 4}

Clearly the set A contains only two elements namely, {2,3} and 4

{2} is not an element of A because A contains no more elements except the set {2,3} and 4

Also,

{2} is not a subset of A because the subsets of A are {} , {{2,3}}, {4}, {{2,3}, 4}
