ElectricPavlov: That "e" is NOT Euler's constant. That is the exponent "e" for computers expressing large numbers such as 10^65, which is written as "1e65". The "e", or Euler's constant is found under the two small arrows under "log" and "10^x". Look at the calculator.
You are correct.....and the question did not specify which 'e' was being sought (sometimes you need to put in big numbers with exponents in interest calcs)...sorry for the confusion. I usually use the calculator on my phone for 'e' as in euler.
