Answer:
{1,3,4,5,6,7}
Step-by-step explanation:
Here , U represents the universal set
L’ = {2,4,6}
L’ is what we have in the universal set but not present in set L
(m n L’)
This is the set that contains the elements that are present in both set ONLY
So this is;
{2}
(M n L’)’ = {1,3,4,5,6,7}
N’ = {1,7}
So the union of both would be;
= {1,3,4,5,6,7}
