How do you evaluate ln5.42 using a calculator to four decimal places?

May 31, 2018

See below:

Explanation:

On most graphing calculators, there is a "shift" or "2nd" button. Press that button and then the button that says ${e}^{x}$.

The reason we press 2nd/shift is because this tells the calculator to apply the inverse of ${e}^{x}$, which is $\ln x$.

Next, type in $5.42$ (make sure this value is in parenthesis), and press enter.

Hope this helps!
