Earth’s radius is approximately 3,959 miles, while Jupiter’s radius is approximately 4.3441×10^4 miles. How much bigger is Jupiter’s radius compared to Earth’s? Express your answer in scientific notation.
To find the difference in radius between Earth and Jupiter, we need to subtract Earth's radius from Jupiter's radius.
The difference is $4.3441 \times 10^4 - 3,959 = 4.3441 \times 10^4 - 3.959 \times 10^0 = 4.3441 \times 10^4 - 3.959 \approx \boxed{4.3 \times 10^4}$.
