write in scientific notation quick check
the speed of light is about 671,000,000 miles per hour. how will you write this number in scientific notation? (1 point)
o 6.71 × 10^(-8)
o 6.71 × 10^(8)
o 6.71 × 10^(-3)
o 6.71 × 10^(3)

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leq a<10$ and $n$ is an integer.

Step2: Move the decimal point

For the number 671000000, move the decimal point 8 places to the left to get $a = 6.71$.

Step3: Determine the exponent

Since we moved the decimal point 8 places to the left, $n = 8$. So the number in scientific notation is $6.71\times10^{8}$.

Answer:

B. $6.71\times 10^{8}$
