Question

How do you calculate `ln 23`?

Answer 1

Well, you'd most likely be allowed to use a calculator on this...

The natural logarithm of `23` is the number that satisfies the expression

`color(red)(ul(e^x = 23`

And

`ln(23) = color(blue)(ulbar(|stackrel(" ")(" "3.135" ")|)`

We can check this by plugging it into the `color(red)("red"` equation:

`e^3.135 = 22.989`
