5 x 2^n +5
thankyou
Hello, xch3m_is_l0v3x!
Is there a typo?
I'll take a guess at what it should be . . .
$\displaystyle \frac{2^{n+2}+12}{5\!\cdot\!2^n +{\color{red}15}}$
We have: .$\displaystyle \frac{2^{n+2} + 2^2\!\cdot\!3}{5\!\cdot\!2^n + 15}$
Factor: . $\displaystyle \frac{2^2(2^n + 3)}{5(2^n + 3)}$
Reduce: . $\displaystyle \frac{2^2}{5} \;=\;\frac{4}{5}$
