Aug 5, 2017

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:

${e}^{3.135} = 22.989$
