#### Question

Prove that:

`(2^n+2^(n-1))/(2^(n+1)-2^n)=3/2`

#### Solution

We have to prove that `(2^n+2^(n-1))/(2^(n+1)-2^n)=3/2`

Let x = `(2^n+2^(n-1))/(2^(n+1)-2^n)`

`=(2^n(1+1xx2^-1))/(2^n(2^1-1))`

`=(1+1/2)/(2-1)`

`rArrx=3/2`

Hence, `(2^n+2^(n-1))/(2^(n+1)-2^n)=3/2`

Is there an error in this question or solution?
