During its orbit around the sun, Venus gets as close as 4 * 10^7 kilometers from Earth and as far as 2.6 * 10^8 kilometers from Earth. What is the difference between these distances? Write your answer in scientific notation. ______ kilometers

Write Distances: First, write down the distances: closest is 4 * 10^7 km, farthest is 2.6 * 10^8 km.Find Difference: To find the difference, subtract the closest distance from the farthest distance: 2.6 * 10^8 km - 4 * 10^7 km.Convert Exponents: Since the exponents are different, we can't subtract them directly. We need to make the exponents the same. Let's convert 4 * 10^7 km to 0.4 * 10^8 km.Subtract Distances: Now subtract: 2.6 * 10^8 km - 0.4 * 10^8 km = 2.2 * 10^8 km.

Write Distances: First, write down the distances: closest is $4 \times 10^7 \, \text{km}$ , farthest is $2.6 \times 10^8 \, \text{km}$ .
Find Difference: To find the difference, subtract the closest distance from the farthest distance: $2.6 \times 10^8 \text{ km} - 4 \times 10^7 \text{ km}.$
Convert Exponents: Since the exponents are different, we can't subtract them directly. We need to make the exponents the same. Let's convert $4 \times 10^7 \, \text{km}$ to $0.4 \times 10^8 \, \text{km}.$
Subtract Distances: Now subtract: $2.6 \times 10^8 \text{ km} - 0.4 \times 10^8 \text{ km} = 2.2 \times 10^8 \text{ km}.$
