A. In 8,326, the 8 is in the thousands place, while in 840,210, the 8 is in the hundred-thousands place.
B. In 2,008, the 8 is in the ones place, while in 28,420, the 8 is in the thousands place.
C. In 284, the 8 is in the tens place, while in 32.098, the 8 is in the thousandths place.
D. In 48.97, the 8 is in the ones place, while in 32.80, the 8 is in the tenths place.
We need to divide 4,971 by 10 until its a number less then 10.
4,971 / 10 = 497.1
497.1 / 10 = 49.71
49.71 / 10 = 4.971
Now, 4.971 is less then 10, so, we can write this into scientific notation.
4.971 * 10^?
We need to know what power we add to 10 to get 4,971. We can solve for looking at the number of times we divided. As you can see above, we divided 3 times so that will be the power of 10.
4.971 * 10³
Best of Luck!
