To find the difference in radius between Jupiter and Earth, we subtract Earth's radius from Jupiter's radius:
4.3441×10^4 miles - 3,959 miles = 4.3441×10^4 miles - 3.959×10^3 miles.
Since the exponents are already the same, we can ignore them for now and focus on the significant figure:
4.3441 - 3.959 = 0.3851.
Now, adjusting the exponents, we have:
0.3851 × 10^4 miles.
Therefore, Jupiter's radius is 0.3851 × 10^4 miles bigger than Earth's radius.
