1)
a = 6 * 10²³
b = 5 * 10¹⁹
-----------------
a * b = (6 * 10²³) * (5 * 10¹⁹) =
= (6 * 5) * (10²³ * 10¹⁹) =
= 30 * 10⁴² = 3 * 10 * 10⁴² = 3 * 10⁴³
------------------
a : b = (6 * 10²³) : (5 * 10¹⁹) =
= (6 : 5) * (10²³ : 10¹⁹) = 1,2 * 10⁴
2)
a = 1,2 * 10²⁰
b = 4 * 10¹⁰
-------------------
a * b = (1,2 * 10²⁰) * (4 * 10¹⁰) =
= (1,2 * 4) * (10²⁰ * 10¹⁰) = 4,8 * 10³⁰
--------------------
a : b = (1,2 * 10²⁰) : (4 * 10¹⁰) =
= (1,2 : 4) * (10²⁰ : 10¹⁰) =
= 0,3 * 10¹⁰ = 0,3 * 10 * 10¹⁰ = 3 * 10¹¹
