Question

A={1,2,3,4} B={3,4,5,6} C={1,3,5} Prove that A-(BUC)=(A-B)intersection(A-C).​

Answer 1

Answer:

they are equal

Heyy!! here is ur answer!!

BUC ={1,2,3,5,7,8}

A-(BUC)={4} -----------------LHS

A-B={2,4}

A-C={1,3,4}

(A-B)n(A-C)={4} ------------RHS

HENCE PROVED

Answer 2

B u C = 1,3,4,5,6

{1,2,3,4} - {1,3,4,5,6} = {1,2} n {2,4}

{2}= {2}
