:
(
i
)

)
∪
(
A
−
B
)
and

Solution
(i) To prove
A
=
(
A
∩
B
)
∪
(
A
−
B
)
Let
x
∈
A
⇒
x
∈
B
or
x
/
∈
B
If
x
∈
B
⇒
x
∈
A
∩
B
If
x
/
∈
B
⇒
x
∈
A
−
B
Hence
x
∈
(
A
∩
B
)
∪
(
A
−
B
)
∴
A
⊆
(
A
∩
B
)
∪
(
A
−
B
)
Let
y
∈
(
A
∩
B
)
∪
(
A
−
B
)
y
∈
(
A
∩
B
)
(or)
y
∈
(
A
−
B
)
[
y
∈
A
and
y
∈
B
]
(or)
[
y
∈
A
and
y
/
∈
B
]
⇒
y
∈
A
∴
(
A
∩
B
)
∪
(
A
−
B
)
⊆
A
Hence
A
=
(
A
∩
B
)
∪
(
A
−
B
)
.
(ii)
B
=
A
⊆
B
⇒
A
∪
(
B
−
A
)
⊆
A
∪
B
Let
x
∈
A
∪
B
⇒
x
∈
A
or
x
∈
B
If
x
∈
A
, then
x
∈
A
∪
(
B
−
A
)
⇒
A
∪
(
B
−
A
)
=
A
∪
B
If
x
∈
A
, then
x
∈
B
−
A
⇒
x
∈
A
∪
(
B
−
A
)
⇒
(
A
∪
B
)
⊆
A
∪
(
B
−
A
)
⇒
A
∪
B
=
A
∪
(
B
−
A
)
.
