1. The problem statement, all variables and given/known data
Find the above limit

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

3. 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 dont 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?
