Please place a ^ before your exponents.
You can prove Kepler's third law is obeyed in this case by showing that the ratio P^2/a^3 is the same for both planets.
You can use any units you want, as long as they are the same for both planets.

Show that Kepler's third law is consistent (approximately) for the orbits of the Mars
and Saturn. Show all your calculations and appropriate units.
P Mars = 690 days; a Mars = 2.3 x 108 km
P Saturn = 10,700 days; a Saturn = 1.4 x 109 km
