Simplifying $e^{2x+1/2}$ So I was taking some derivatives and the question was

$e^{2x+\frac{1}{2}}$
  convert this to $a\cdot b^x$ where $a$ and $b$ are constants.

This is apparently needed to take the derivative of it without using the chain rule.
Any idea how to tackle this? Tried to manipulate it but I always end up with both of the constants having powers.

$$e^{2x+\frac12}=e^{2x}\cdot e^{\frac12}=\sqrt e\cdot(e^2)^x$$So $a=\sqrt e, b=e^2$
