 Question from Kara, a student: How do I write this in exponential form? log 1/8 = -3

Hi Kara,

Use that fact that the natural logarithm and exponential functions are inverses. That is for any number $x,$

$\log(e^x) = x$

and

$e^{\log(x)} = x.$

For your problem start by raising both sides of the equation to the power of $e.$
