Question

In 1968, the estimated population of the world was 3,559,028,982 people. When this number is written in expanded form using exponents, one power of 10 would not be represented. Which power of 10? Why?

Answer 1

Answer:

10 to the power of 5 or 10^5.

Step-by-step explanation:

The digit in the hundred thousand digit place is a 0. This means that it is not represented in the expanded form of 3,559,028,982.

Answer 2

Answer:

  10^5 has a coefficient of 0

Step-by-step explanation:

10^5 would have a coefficient of 0, so might be left out of the expansion.

_____

The expansion is ...

  3×10⁹ +5×10⁸ +5×10⁷ +9×10⁶ +0×10⁵ +2×10⁴ +8×10³ +9×10² +8×10¹ +2×10⁰

Additional comment

I like to show the 0 terms for completeness, and to demonstrate the decreasing powers of 10 associated with each of the number places (left-to-right). Apparently, your curriculum author intends that you leave out the zero term in your expansion.
