Answer:
To find the difference between the diameters of Saturn and Uranus, we can subtract the diameter of Uranus from the diameter of Saturn:
Diameter of Saturn - Diameter of Uranus
(1.21 x 10^5 km) - (5.11 x 10^4 km)
= (1.21 - 0.511) x 10^5 km
= 0.699 x 10^5 km
= 6.99 x 10^4 km
Therefore, the difference between the diameters of Saturn and Uranus is approximately 6.99 x 10^4 kilometers.
