To determine how much bigger Jupiter's radius is compared to Earth's radius, we will first express Earth's radius in scientific notation, then calculate the ratio of the two radii.
-
Convert Earth's radius to scientific notation: \[ \text{Earth's radius} = 3,959 \text{ miles} = 3.959 \times 10^3 \text{ miles} \]
-
Jupiter's radius (already given in scientific notation): \[ \text{Jupiter's radius} = 4.3441 \times 10^4 \text{ miles} \]
-
Calculate how much bigger Jupiter's radius is compared to Earth's: \[ \text{Ratio} = \frac{\text{Jupiter's radius}}{\text{Earth's radius}} = \frac{4.3441 \times 10^4}{3.959 \times 10^3} \]
-
Perform the division: Divide the coefficients: \[ 4.3441 \div 3.959 \approx 1.096 \]
Divide the powers of ten: \[ 10^4 \div 10^3 = 10^{4-3} = 10^1 \]
-
Combine the results: \[ \text{Ratio} \approx 1.096 \times 10^1 \]
So Jupiter's radius is approximately \( 1.096 \times 10^1 \) times bigger than Earth's radius. In scientific notation, this can be expressed as:
\[ \boxed{1.096 \times 10^1} \]
