Rewrite exponential in form $a+bi$ My professor lately has become really bad at giving examples and any help with an example would be great.
if I have $e^{(2+3i)}$ how do I rewrite it as $a+bi$? is it just $2+3i$ in this case?

No, it is not simply $2+3i$. Use Euler's formula, i.e.
$$e^{ix} = \cos x + i \sin x$$
so that
$$e^{a+bi} = e^ae^{bi} = e^a(\cos b + i \sin b).$$
