Could someone help me and explain how to write teh following in terms of x and y. I have seen some examples but I dont seem to be able to do this one on my own.

$\displaystyle |e^{5z+3i+2}|$ and $\displaystyle |e^{iz^2}|$

and show that $\displaystyle |e^{5z+3i+2} + e^{iz^2}|$ $\displaystyle \not\leq$ $\displaystyle e^{5x + 2} + e^{-2xy}$
