Break down left side:
Now, let's look at the left side of the equation.

2
(
n

)
2\times 2^{(n+1)}
2

2
(
n

can be written as

(
n

2^{1}\times 2^{(n+1)} = 2^{(n+1+1)} = 2^{(n+2)}

Set exponents equal:
We can now set the exponents equal to each other since the bases are the same.
\newline
So,
n
+
2
=
45
n+2 = 45
n
+
2
=
45
Subtract to solve for n:
Subtract
2
2
2
from both sides to solve for
n
n
n
.
\newline
n
=
45
−
2
n = 45 - 2
n
=

−

\newline
n
=
43
n = 43
n
=
