The speed of light is about 671,000,000 miles per hour how will you write this number in scientific notation?
A. 6.71 x 10^8
B. 6.71 x 10^-8
C. 6.71 x 10^3
D. 6.71 x 10^-3
The correct answer is A. 6.71 x 10^8
To write the speed of light in scientific notation, we need to express it as a number between 1 and 10, multiplied by 10 raised to a specific power. The given speed of light is about 671,000,000 miles per hour.
To convert this to scientific notation, we need to move the decimal point to the left until there is only one non-zero digit to the left of the decimal point. Counting 6 places from the right, we get:
6.71
The decimal point initially appeared after the 1, but we moved it 6 places to the left. Therefore, the number in scientific notation is:
Answer: A. 6.71 x 10^8
To write a number in scientific notation, we want to express it as a number between 1 and 10 multiplied by a power of 10.
The speed of light, which is approximately 671,000,000 miles per hour, can be written as 6.71 multiplied by 10 raised to the power of 8.
So the correct answer is A. 6.71 x 10^8.
