Sagot :
Answer:
1.{1,2,3,4}
2.{1,2,3,4,5}
3.{2,3,4,5}
4.{2,3,4,5,6}
5.{2,3}
6.{3}
7.{}
8.{1,4}
9.{1,2,3,4,5,6}
10.{3,6}
✏️ ANSWER:
1.PUQ={1,2,3}U{2,3,4}={1,2,3,4}
2.PUR={1,2,3}U{3,4,5}={1,2,3,4,5}
3.QUP={2,3,4}U{3,4,5}={2,3,4,5}
4.QUS={2,3,4}U{4,5,6}={2,3,4,5,6}
{AUB consists of elements of set A and set B}
5.PnQ={1,2,3}n{2,3,4}={2,3}
6.PnR={1,2,3}n{3,4,5}={3}
7.SnP={4,5,6}n{1,2,3}=∅
{AnB consists of elements belonging to both set A and set B}
8.Q-P={2,3,4}-{1,2,3}={4}
9.P-S={1,2,3}-{4,5,6}={1,2,3}
10.R-S={3,4,5,}-{4,5,6,}={3}
{A-B=A-AnB}
