The given number 39,800,000
To put the number in the scientific notation make it in the form
[tex]a\times10^n[/tex]
Where 1 < a < 10, n is an integer
Divide the given number by 1,000,000 to make it between 1 and 10, then multiply it by 10 ^ 7
[tex]\frac{39800000}{1000000}=3.98\times10^7[/tex]
The answer is C
