How do I set y=e^x in terms of y? (change "y=" into "x=" )

OpenStudy (superdavesuper):

do u know the natural log function, ln?

OpenStudy (anonymous):

@superdavesuper Yes. Is that what I use? I thought natural log would be the opposite of e, but wasn't sure...

OpenStudy (isaiah.feynman):

Take the natural logarithm of both sides you get lny=x or x=lny
