Step-by-step explanation:
A={3,5,7,9}
B={4,5,6,7,8}
Then we should find n(A intersection B union A)
First
A intersection B
{3,5,7,9} intersection {4,5,6,7,8}
{5}
Then A intersection B union A
{5}union{3,5,7,9}
{3,5,7,9}
Then n(A intersection B union A)
n(3,5,7,9)
No.of elements in this set is
n(3,5,7,9)=4
