Question

if A={2,5,6,7} and B={3,5,7,8},then verify the commutative property of union sets

​

Answer 1

Answer:

we know that,

The commutative property of union set is

AUB= BUA

Given,

A={2,5,6,7} and B={3,5,7,8}

then,

L.H.S.= AUB

={2,5,6,7}U{3,5,7,8}

= {2,3,5,6,7,8}

and,

R.H.S= BUA

= {3,5,7,8}U{2,5,6,7}

= { 2,3,5,6,7,8}

Since,

L.H.S= R.H.S

hence,

AUB= BUA
