# Thread: Limit...

1. ## Limit...

$\lim [\frac{10^n+1}{2*10^n-1}]$

here is my work:
$\lim \frac{10^n(1+1)}{10^n(2*1-1)}$ = $\frac{2}{1}$
But that was wrong..correct answer was $\frac{1}{2}$

2. There is a mistake when you factorized : $10^n+1 = 10^n\left(1+\frac 1{10^n}\right)$

Assuming $\color{blue}n\to\infty$:
Devide top and bottom by $\color{blue}10^n$.
