Can a convenient value for(adsbygoogle = window.adsbygoogle || []).push({}); abe found without resorting to substituting numerical values forhin this expression?

EDIT: I am trying to indicate, "as h approaches zero".

EDIT: neither of the formattings worked; hopefully someone understands what I am asking?

Lim[tex]_{h\rightarrow\0}[/tex][tex]\frac{a^{x}-1}{h}[/tex]

In case that formatting failed, an attempt at rewriting it is:

Lim_{h[tex]\rightarrow[/tex]0}[tex]\frac{a^{x}-1}{h}[/tex]

The most desired value for this limit is 1, and the suitalbe value forawould need to bea = e. I have seen this accomplished using numerical value substitutions , but can the same be accomplished using purely symbolic steps, without any numerical value subsitutions?
