Question

900 e 0.025.20 =

Can someone please tell me how to use this on TI-84 calculator?
A. 900 e^(0.02520)
B. 900 * e^(0.025/20)
C. 900 * e^(0.02520)
D. 900 * e^(0.025/20)

Answer 1

To calculate 900*e^(0.025*20) with a TI-84 calculator, input 900, multiply by e (using the 2nd and LN keys), and then enter the exponent 0.025*20, finishing with the ENTER key. Convert the result to scientific notation if necessary.

Step-by-step explanation:

To calculate the expression 900 e^(0.025*20) using a TI-84 calculator, follow these steps:

1. Turn on the calculator and ensure it's in the correct mode for calculations.
2. Enter the number 900.
3. Press the multiplication button *.
4. For the constant e, press the 2nd key followed by the LN key (which accesses the e^ function).
5. Enter the exponent by typing 0.025, press the multiplication key *, and then type 20.
6. Finish by pressing the ) key (if needed) and the ENTER key to get the result.

Remember, scientific notation might be necessary if dealing with very large or small results in different contexts. To convert to scientific notation, you may divide or multiply the result by a power of ten and adjust the exponent accordingly.
