A = ln(7.5)
You can use the computers scientific calculator and click 7.5, then click ln
or go to www.calculator.com, click on Scientific Calculator, and this has a LN right above the e^x.

If you have a TI scientific/graphing calculator, hit the 2nd key (it's usually yellow) and then hit the LN button. All of the buttons usually have their reverse functions above them in yellow.

The calculator should have an ln button on it.

If you want to go back from "A" to 7.5, you have to hit exponetial, usually e^x or exp on most calculators.
