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#
