I'm stuck in the follow equation: $\dfrac{2^{n + 4} + 2^{n + 2} + 2^{n - 1}}{2^{n - 2} + 2^{n - 1}}$
As all the bases are equal, I got $\dfrac{3n + 5}{2n - 3}$
Where I've to go now ?
Thanks
EDIT:
Then, my initial idea was totally wrong, starting again, in the right way I got:
$\dfrac{2^n(2^4 + 2^2 + 2^{-1})}{2^n(2^{-2} + 2^{-1})}$
but it's still wrong, I didn't get the right idea on the divisions you have shown to me in the answers.
