To find out how much bigger Jupiter's radius is compared to Earth's radius, we can calculate the ratio of the two radii.

  1. Convert both radii to the same units (miles):

    • Earth's radius = 3,959 miles
    • Jupiter's radius = \(4.3441 \times 10^4\) miles
  2. Calculate the ratio: \[ \text{Ratio} = \frac{\text{Jupiter's radius}}{\text{Earth's radius}} = \frac{4.3441 \times 10^4 \text{ miles}}{3,959 \text{ miles}} \]

  3. Perform the division: \[ \text{Ratio} = \frac{4.3441 \times 10^4}{3,959} \]

Calculating this using a calculator:

  • First, calculate \( \frac{4.3441 \times 10^4}{3,959} \):
    • The numerical division part: \( \frac{43441}{3959} \approx 10.96 \) (keeping full precision).
  • Convert that into scientific notation by multiplying by \( 10^4 \) (which simplifies where needed):

Putting this together: \[ \text{Ratio} \approx 10.96 \times 10^{0} \approx 1.096 \times 10^{1} \]

Thus, Jupiter's radius is approximately \(1.096 \times 10^{1}\) times larger than Earth's radius when expressed in scientific notation.

Final answer: \[ 1.096 \times 10^{1} \text{ miles} \]
