You don't have a "quotient"! You just have e^{x} multiplied by a CONSTANT.

d/dx sqrt(2) = 0

I don't know the english name for this rule but call e^x = u and sqrt(2) = v

d/dx u/v = (u'v-uv')/v^2

If C is a constant, then (Cf(x))'= Cf '(x) and (f(x)/C)'= f'(x)/C. Most people learn those long before (well, maybe a week) before they learn the product rule or quotient rule.
