meters wide. Which value represents the estimated width of the Kuiper Belt, in meters, in scientific notation?
Responses
3.0×10−6
meter
3 point 0 times 10 to the negative 6 power meter
30×10−5
meter
30 times 10 to the negative 5 power meter
30×105
meters
30 times 10 to the 5th power meters
3.0×106
meters
3.0×10^6 meters
The estimated width of the Kuiper Belt, in meters, in scientific notation is 3.0 x 10^6 meters.
To represent the estimated width of the Kuiper Belt, in meters, in scientific notation, we need to determine the appropriate power of 10 to use. In scientific notation, the number should be between 1 and 10, so we need to move the decimal point in 3,000,000 (3 million) to get a number between 1 and 10.
To move the decimal point, count the number of places you need to move it to get a number between 1 and 10. In this case, we need to move the decimal point 6 places to the left.
Therefore, the estimated width of the Kuiper Belt in scientific notation would be 3.0 × 10^6 meters.
