What does 1.98E8 on a calculator look like on your paper in scientific notation?
Show work
1.98E8 is equivalent to 198,000,000 in standard notation.
To represent this number in scientific notation, we move the decimal point so that there is only one non-zero digit to its left. In this case, we move the decimal point 8 places to the left, resulting in 1.98.
Since we moved the decimal point 8 places to the left, we need to multiply the number by 10^8 to maintain its value. Thus, the scientific notation for 1.98E8 is:
1.98 x 10^8
To express 1.98E8 in scientific notation on paper, follow these steps:
1. Write down the number in decimal form: 1.98
2. Count the number of decimal places you need to move the decimal point to get the number between 1 and 10. In this case, you need to move the decimal point 8 places to the right.
3. Write down the exponent of 10, which is the number of places you moved the decimal point. In this case, the exponent will be 8.
4. Combine the decimal form and the exponent of 10 to express the number in scientific notation. It will look like this: 1.98 x 10^8.
So, 1.98E8 on a calculator can be written as 1.98 x 10^8 in scientific notation.
To express 1.98E8 in scientific notation on paper, you need to convert it into the proper format. Here's how you can do it:
Step 1: Write down the number as it appears on the calculator: 1.98E8.
Step 2: Identify the decimal point in the number. In this case, it is already after the first digit, so nothing needs to be done.
Step 3: Count the number of places you would need to move the decimal point to get a number between 1 and 10. In this case, you would need to move the decimal point 8 places to the left.
Step 4: Determine the power of 10 by the number of places you moved the decimal point. Since you moved the decimal point 8 places to the left, the power of 10 will be 8.
Step 5: Write down the number, shifting the decimal point to the desired location and adding the power of 10 as an exponent. The final result is 1.98 x 10^8.
So, 1.98E8 on a calculator written in scientific notation on paper is 1.98 x 10^8.
