Question

If U={1,2,3,4,5}.
A={1,2,5}
B={3,4,5}.
prove that :
A' n B' = (A U B)'​

Answer 1

Answer:

Ans AnB = AUB = 1

Step-by-step explanation:

f U={1,2,3,4,5}.

A={1,2,5}

B={3,4,5}.

prove that :

A' n B' = (A U B)'

Answer 2

Answer:

U= { 1; 2; 3;4;5;}

A= { 2;3}

B= { 3;4;5}

AUB= { 2;3} U { 3;4;5} = {2;3;4;5}

therefore(;AUB)= {1;6}

B= {1;2;6}

therefore AUB = { 1;4;5;6,} U { 1,2,6}={1,6}
