Calculators TI-30XA help

  1. Sep 20, 2010 #1
    Im not allow to use TI-84 anymore and have to use TI-30XA. I need help putting in 50e^(-.00043448 * 5000). I did -.00043348*5000 first and got -2.1674. I have problem with this part. On the TI-84 I can do it but having trouble on my new calculator. I type 50e but it gives me 5.184705529^21. What do I do with the -2.1674? Do I add it, multiply or take the e of it? The answer is 5.7

    Work your way inside-out. So take e first, then multiply by 50.
