Question

If a and b are any two sets, then a ∩ (a ∪
b.is equal to

Answer 1

Let AUB={a,b} and A={a}
Clearly the common element ;An(AUB) is a i.e, Set A

Answer 2

∴ $a\cap(a\cup b)=\left \{A \right \}$

Step-by-step explanation:

Given;

$a$ and $b$ are any two sets.

$a\cap(a\cup b)=?$

If  $a=\left \{A \right \}$ and $b=\left \{ B \right \}$

Then   $a\cup b=\left \{ A,B \right \}$

∴ $a\cap(a\cup b)=\left \{A \right \}$
