Final answer:
The expression 1.892 × 10^8 does not match any of the options provided. When using a calculator to work with scientific notation, you can enter expressions directly or calculate the powers of 10 separately. Understanding scientific notation and calculator use is essential.
Step-by-step explanation:
The expression 1.892 × 10^8 is already in scientific notation, and none of the given options (a to d) match this number. To resolve a different calculation using scientific notation on a calculator, you follow certain steps. For instance, when multiplying or dividing numbers in scientific notation, you can either calculate the powers of 10 separately or enter the entire expression into most scientific calculators directly, which will automatically compute and provide the result in scientific notation.
Here are some examples of using a calculator to evaluate expressions in scientific notation:
- Expressing in standard notation: For numbers such as 7.11 × 10^-2, you would move the decimal place two positions to the left, resulting in 0.0711.
- Converting to scientific notation: For a number like 93,000,000, you would find the decimal variant (9.3) and then count the number of places the decimal has moved (7) to express it as 9.3 × 10^7.
It is crucial to understand scientific notation and how to use a calculator effectively to work with these expressions accurately.
