Step-by-step explanation:
1) 149,600,000 km to scientific notation:
we count the number of movement from the last number to the first number
The number of movement = 8
![\begin{gathered} \text{scientific notation = 1.4}9600000*10^{number\text{ of movement}} \\ =\text{ 1.496 }*10^8\operatorname{km} \end{gathered}]()
93,000,000 miles to scientific notation:
number of movement = 7
