Question
If $A=\{a, b\}, B=\{c, d\}$ and $C=\{d, c\}$, then find $A \times(B \cup C)$.
✓

Answer

Given, $A=\{a, b\}, B=\{c, d\}$
and $C=\{d, c\}$.
Now, $B \cup C=\{c, d\}$
$\begin{array}{l}\therefore A \times( B \cup C )=\{a, b\} \times\{c, d\} \\ =\{( a , c ),( a , d ),( b , c )( b , d )\}\end{array}$
