Answer:
[tex]1.486*10^8[/tex]
[tex]9.118*10^3[/tex]
Step-by-step explanation:
By definition, the form of Scientific notation is:
[tex]a*10^n[/tex]
Where the base is 10, "a" is any number from 1 to 10 but not including 10, and "n" is an integer.
Therefore to write a number in Scientific notation, the decimal point must be after the first digit and the power "n" must indicate how many places the decimal point is moved.
We know that:
[tex]148.6\ million=148,600,000\ millions[/tex]
Then, we need to move the decimal point 8 places to the left:
[tex]=1.486*10^8[/tex]
To write $9,118 in scientific notation, we need to move the decimal point 3 places to the left:
[tex]=9.118*10^3[/tex]
