I know that the $\ln{(7x)}$ will go to just $7x$, but I'm confused about how the $17$ fits into the answer.

$$e^{17+\ln 7x} = e^{17} e^{ \ln 7x} = 7xe^{17}$$

And it does not simplify any more.


I assume you mean $e^{17+\ln(7x)}$ and you want to simplify?

You can use the following:

$e^{a+b} = e^ae^b$
