Question

A=(1, 5, 7, 8), B=(1, 2, 3) and C=( 5, 6, 7) then show A union (B intersection C ) =(A union B) intersection (A union C)​

Answer 1

Answer:

taking LHS

B intersection c=fie

A union b intersection c ={1,5,7,8}

taking RHS

A union B={1,2, 3,5,7,8}

A union C={1,5,6,7,8}

(a union b) intersection ( A union C)={1,5,7,8}

LHS=RHS

hence verified
