Hey people!
Can you help, please?!
$\displaystyle
\frac{2^n+^4 - 2.2^n} {2.2^n+^3}
$
It's easy?!
I just can't transform those stuffs in numbers !!!

If this is your question
$\displaystyle
\frac{2^{n+4} - 2\times2^n} {2.2^{n+3}}
$
$\displaystyle
a^{x} \times a^{y} = a^{x+y}$
$\displaystyle
=\frac{2^{n+4} - 2^{n+1}} {2^{n+4}}
$
$\displaystyle
=\frac{2^{n+4} - 2^{n+1}} {2^{n+4}}
$
Divide numerator and denominator by $\displaystyle 2^{n+1} $
$\displaystyle
=\frac{2^{3} - 1} {2^{3}}
$
$\displaystyle
=\frac{8 - 1} {8}
$
$\displaystyle
=\frac{7} {8}
$
