Answer

Explanation:

Step1: Rewrite to same exponent

Convert $2 \times 10^5$ to $20 \times 10^4$

Step2: Subtract the two values

$(20 \times 10^4) - (6.28 \times 10^4) = (20 - 6.28) \times 10^4$

Step3: Calculate the difference

$13.72 \times 10^4$

Step4: Convert to proper scientific notation

$1.372 \times 10^5$

Answer:

$1.372 \times 10^5$ square kilometers (or 137200 square kilometers in standard notation)
