Answer:
A ∪ B = B
Step-by-step explanation:
Given, A ⊆ B
therefore, A ∪ B = B
Let me explain you with an Example!!
Let A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5, 6, 7, 8}
clearly, A ⊆ B
A ∪ B = {1, 2, 3, 4, 5) ∪ {1, 2, 3, 4, 5, 6, 7, 8}
= {1, 2, 3, 4, 5, 6, 7, 8}
= Set B!
Therefore, if A and B are 2 sets, such that A is a subset of B, then A ∪ B is B!
Hope you Understood!!
