Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I was doing some exercises on limits when I stumbled upon the following questions:

(limits are always x->infinity)

lim (2^x+1)/(3^x+1)

2nd one:

lim (-9/8)^x

The first one should be zero (3^x expands faster than 2^x), and the 2nd one doesn't seem to exist (according to maple and the solutions , I suppose it has something to do with the graph being all chopped up and not knowing if x->infinity is even or odd?).

Is there a way to find these answers trough calculation instead of uncertain logic :tongue: ?

Another exercise similar to the first one:

lim (8/9)^x
