Answer:
2.11670 x 10^8
Explanation:
211,670,000
To convert this standard notation number into a scientific number, you'll need to move the decimal 8 times to the left.
Remember, that the base of 10 always stays as 10. Only the exponent changes. We will be placing the 8 as the exponent since you moved the decimal 8 times to the left, making it 10^8 (if it were to the right, it would've been negative. I believe you'll learn more about that in class.) We can remove the zeros, thus leading to the answer of 2.11670 x 10^8.
