SUMMARY

The discussion revolves around using the TI-30XA calculator to solve the expression 50e^(-0.00043448 * 5000). The user initially calculated -0.00043448 * 5000, resulting in -2.1674, but faced difficulties inputting the expression correctly. The correct approach is to first calculate e raised to the power of -2.1674, then multiply the result by 50, leading to the final answer of approximately 5.7.

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.
