    \[y=e^{f(x)} => y'=f'(x) e^{f(x)} \]

    This right here will work every time for something in the form of \[y=e^{f(x)}\]

    U differentiate the power of the e first and then multiply it with the function that is how u differentiate the power of the e..

    \[y'=(5-3 \ln(x))'e^{5-3\ln(x)}\] using the rule I wrote down

    the derivative of 5-3lnx would be -3* 1/x ?
