If y=lnx then how does x=e^y watch

1. ^^^^^
2. Do you know what a logarithm is?
3. You have to raise both sides by power e to remove the ln.
4. 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

You have to raise both sides by power e to remove the ln.
e is not a power in this case
6. 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 . That means can be written as . 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
