Limit of Function: Find Solution

[PeteSampras]

Homework Statement

Find the above limit

Homework Equations

$\lim_{t\rightarrow 0} \dfrac{\exp(-A/t)}{t^{n/2}}$ with A>0

The Attempt at a Solution

I tried using the change of variable $u=1/t^{n/2}$, and then next use LHopital rule, but i don't find the way..

Have you tried taking the natural log of the expression? What about letting u = 1/t rather than the more complex expression?
