What does 1.98E8 on a calculator look like on your paper in scientific notation? Show your work.
1.98E8 in scientific notation can be expressed as:
1.98 × 10^8
To obtain this representation, we move the decimal point 8 places to the right as denoted by the exponent 8 in 10^8.
To convert 1.98E8 to scientific notation using a calculator, follow these steps:
Step 1: Start with the number 1.98E8.
Step 2: The exponent of 1.98E8, which is represented by "E8," tells us how many places to move the decimal point to the right. In this case, the exponent 8 indicates that we need to move the decimal point 8 places to the right.
Step 3: Move the decimal point in 1.98E8 to the right 8 places, and fill in any empty places with zeros.
1.98E8 = 198,000,000
Step 4: Rewrite the number as a decimal between 1 and 10. In this case, we can write it as 1.98.
Step 5: Multiply the decimal number from step 4 by 10 raised to the power of the exponent from step 2. In this case, 10^8.
1.98 × 10^8
Therefore, 1.98E8 in scientific notation is equal to 1.98 × 10^8.
To convert the number 1.98E8 into standard scientific notation, follow these steps:
Step 1: Identify the base number.
In this case, the base number is 1.98
Step 2: Determine the exponent.
The exponent is indicated by the value after the "E." In this case, it is 8.
Step 3: Write the base and the exponent in scientific notation format.
To convert the number 1.98E8 to standard scientific notation, we write it as:
1.98 x 10^8
So, 1.98E8 in scientific notation is written as 1.98 x 10^8.
