Question

If A={a,b,c,d}, B={c,e,i,o}then show that AUB=BUA

Answer 1

given★

• A={a,b,c,d}, B={c,e,i,o}

verify★

• AUB=BUA

$\huge\star\pink{SOLUTION★}$

LHS↓

• AUB

• {a,b,c,d}U{c,e,i,o}

• {a,b,c,d,e,i,o} ----------------(1)

RHS↓

• now BUA

• {c,e,i,o,a,b,d}

• can we be this written as

• {a,b,c,d,e,i,o} ----------------(2)

EQ (1) and (2)।hs =rhs (hence proved )
