The mass of jupiter is 1.898 × 1027 kilograms, and the mass of saturn is 5.68 × 1026 kilograms. how much greater is jupiter's mass than saturn's mass?

Masse Jupiter = 1.898 x 10²⁷   OR 18.98 x 10²⁶

Mass Saturn = 5.68 x 10²⁶

Difference of Masses = Jupiter - Saturne  OR 1.898 x 10²⁷ - 5.68 x 10²⁶

In order to be able to proceed to the subtraction, both exponents of 10 should be equal, the Mass of Jupiter 1.898 x 10²⁷   OR 18.98 x 10²⁶

Now 18.98 x 10²⁶ - 53.68 x 10²⁶ ==> (18.98 - 5.68) x 10²⁶ ===>

Masses = Jupiter - Saturne  = 13.3 x 10²⁶  OR 1.33 x 10²⁷
