. ,
B = {2,4,6,8...}
Find A'U{AUB} intersection B'​

Answer 1

Answer:

Step-by-step explanation:

LetN={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18}

∵A={1,3,5,7,9,........,17}

B={2,4,6,8,........18}

A  

′

 

={2,4,6,8,.......18}

B  

′

 

={1,3,5,7,.......17}

∵A=B  

′

 

&B=A  

′

 

 

(A∪B)={1,2,3,4,5,6,............18}

(A∪B)∩B  

′

 

={1,3,5,7,..........17}

A  

′

 

∪[(A∪B)∩B  

′

 

]={1,2,3,4,5,6,..........18}

∴A  

′

 

∪[(A∪B)∩B  

′

 

]=N
