Can you find two integers
m
,
n
such that
2
m
+
n
=
2
m
n
?
Open in App
Solution
Equating the powers of
2
m
+
n
=
2
m
n
that is
m
+
n
=
m
n
.
Now we have to find such integers so that the sum of the integers is equal to their product and those integers are
0
and
2
:
Let us first take
m
=
2
and
n
=
2
, we get
2
+
2
=
2
×
2
⇒
4
=
4
which is true
Now take
m
=
0
and
n
=
0
, we get
0
+
0
=
0
×
0
⇒
0
=
0
which is true
Hence the integers are
m
=
0
,
2
and
n
=
0
,
2
.
