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
[tex]\begin{gathered} \text{scientific notation = 1.4}9600000\times10^{number\text{ of movement}} \\ =\text{ 1.496 }\times10^8\operatorname{km} \end{gathered}[/tex]
93,000,000 miles to scientific notation:
number of movement = 7
[tex]\begin{gathered} \text{scientific notation = }9.3000000\times10^{number\text{ of movement}} \\ =\text{ 9.3}\times10^7\text{miles} \end{gathered}[/tex]
