Answer:

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 #lnx#.

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

Hope this helps!
