Correct Answer
Option A
Explanation
To determine why Option 1 is the correct answer, we need to evaluate the expression \( p = (12.34 \times 10^{10}) - (5.67 \times 10^{9}) \) and express the result in standard form. ### Step-by-Step Calculation: 1. Express Both Terms with the Same Power of 10: - The first term is already in the form \( 12.34 \times 10^{10} \). - Convert the second term to the same power of…Read More
