The correct statement comparing the two numbers \(4.23 \times 10^{-5}\) and \(4.23 \times 10^{5}\) is:
One of the numbers in standard form is large (>1) and the other number in standard form is small (<1).
Here's the reasoning:
- \(4.23 \times 10^{-5}\) is a small number, as it is equivalent to 0.0000423, which is less than 1.
- \(4.23 \times 10^{5}\) is a large number, as it is equivalent to 423,000, which is greater than 1.
