Answer 1

Answer:

please mark as brainliest

Step-by-step explanation:

A.T.Q.

A={1,2,3,4,6,12}

B={1,2,3,6}

AuB={1,2,3,4,6,12}=A

AnB={1,2,3,6}=B

Answer 2

Answer:

i) AUB = A

ii) AnB=B

Step-by-step explanation:

Given A = {x:x is a factor of 12}

=> A = { 1,2,3,4,6,12}

B = {x:x is a factor of 6 }

=> B = { 1,2,3,6}

Now ,.

i ) AUB = {1,2,3,4,6,12}U{1,2,3,6}

= {1,2,3,4,6,12}

= A

ii)AnB={1,2,3,4,6,12}U{1,2,3,6}

= {1,2,3,6}

= B
