Question

16. If A= {a, (a, b)). write all the subset of A.​

Answer 1

$\mathfrak{\huge{\red{\underline{\underline{Answer :}}}}}$

A = {a , {a, b}}

In set A , there are two elements a and {a,b}

so, number of elements in set A , n = 2

We know, if n is the number of elements in any set A

Then, number of subset = 2ⁿ

∴ number of subset of A = 2² = 4

e.g., Φ , {a} , {{a,b}} , {a, {a, b}}
