    \(\large\ln(x)\) is same as \(\large\log_{e}(x)\)

    Ok ok, so would I take the 'e' and sort of "bump" it over to the 'y' slot making e^y?

    \(\large\color{black}{ \displaystyle y=\ln(x) }\) \(\large\color{black}{ \displaystyle y=\log_{e}(x) }\) then apply the rule: \(\huge\color{black}{ \displaystyle \color{red}{\rm a}=\log_{\color{green}{\rm b}}(\color{blue}{\rm c})~~~~~\Longrightarrow ~~~~~ \displaystyle \color{green}{\rm b}^{\color{red}{\rm a}}=\color{blue}{\rm c} }\)

    this rule that I drew with many colors, is what you should use for your final answer.

    actually, the way you wrote the options, none of them are correct-;(

    I would first set it as \[y = \log_{e} x\] and then turn it into \[e ^{y} = x\]

    Oh and option C should be x=e^y. Sorry
