Final answer:
To evaluate the expression e^-1.6, use a scientific calculator and round the resulting value to five decimal places, which involves checking the sixth decimal place to determine the rounding.
Step-by-step explanation:
To evaluate e raised to the power of negative one point six (e-1.6), we can use a scientific calculator or a relevant software tool that can perform exponential calculations. The base e is approximately equal to 2.71828, and when raised to the negative powers, it represents a fraction or a decay process.
To solve this, we input the calculation into the calculator as e raised to the negative 1.6 power. After performing the calculation, we round the answer to five decimal places as required. Please remember to check your calculator's settings to ensure it is set to the correct mode for this type of calculation.
If rounding, keep in mind that if the sixth decimal place is 5 or higher, you would round up the fifth decimal place by one. If it is lower than 5, you keep the fifth decimal place as is.
