    You have to raise both sides by power e to remove the ln.

    That's literally the definition of the natural logarithm.
    Think of it like this:
    If x=y then ex = ey
    So if y=lnx then ey = elnx
    elnx is x.
    Therefore if y=lnx then ey=x

    e is not a power in this case:laugh:

    OP, multiply both sides by e. This will leave you with e^y= x (as ln and e cancel each other out)

    Not multiply, take exponentials (which is what you probably meant anyway)

    ln is just a way of saying "log to base e", so y = \log_e{x}. That means x can be written as e^y. If that sounds unfamiliar to you, you might want to look over logarithms again.

    Yeah that it's been a while since I did natural logarithm
