Rewrite in logarithmic form: e^(-1) = c

[Vi Nguyen]

Rewrite in logarithmic form:

e^(-1) = c

 

[Greg]

\(\displaystyle \ln\left(e^{-1}\right)=\ln(c)\)

\(\displaystyle -1=\ln(c)\)

You have posted a number of logarithm problems without, apparently, know what a "logarithm" is! If you are not taking a class that involves logarithms, where are you getting these problems?

$y= a^x$ is equivalent to $log_a(y)= x$.
