# Thread: Need help on TI-30XA

1. ## Need help on TI-30XA

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

try typing in ... ( note that each set of bold brackets [...] is a non-numerical key )
