Question

for any two sets A and B, AUB=A iff​

Answer 1

Answer:

If A contains same elements as B

Step-by-step explanation:

For example - A= {1,2,3},

B= {1,2,3}

AUB= A

Answer 2

Answer:

example

set A=(1,2,3,4,5,6)

set B=(1,2,6)

then AUB = (1,2,3,4,5,6) =A

When the elements in A are also in B then AUB=A
