Step-by-step explanation:
First, we can convert all of the numbers to decimal from (it will be easier to understand that way).
Now, we can easily see which numbers are bigger/smaller.
Answer: 8.67 x
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point. In this problem, we can write 8,670,000,000 as 8.670000000. Notice that there is only one digit to the left of the decimal point. Next, we count the number of places the decimal point would need to move to get back to our starting number which is 8,670,000,000. In this case, the decimal point would need to move 9 places to the right in order to get back to our original number. This would make our exponent positive 9 because we would need to move to the right 9 places. Lastly, we can drop any zeroes that are at the end of the decimal. Therefore, 8,670,000,000can be written in scientific notation as 8.67 x .
