1 answer

The correct answer is:

C. One of the numbers in standard form is large (>1) and the other number in standard form is small (<1).

Explanation:

  • \(4.23 \times 10^{-5}\) is equal to 0.0000423, which is less than 1 (a small number).
  • \(4.23 \times 10^{5}\) is equal to 423,000, which is greater than 1 (a large number).
