Solution
Given that:
3
m
×
2
n
2
m
×
3
n
( m and n are distinct integers)
=
3
(
m
−
n
)
2
(
m
−
n
)
........Using [
a
−
m
=
1
a
m
]
=
(
3
2
)
m
−
n
this cannot be integer as
3
2
=
1.5
so
(
1.5
)
(
m
−
n
)
whether
m
>
n
or
n
>
m
in all cases result will be decimal. So
3
m
×
2
n
2
m
×
3
n
is not an integer.
