Answer: Choice C


3 * 10^8

=================================================

Step-by-step explanation:

Divide 7.5 over 2.5 to get 3

Dividing the other terms means we subtract the exponents using this rule


(a^b)/(a^c) = a^(b-c)

So,


(10^(12))/(10^4) = 10^(12-4) = 10^8

Overall,


(7.5 * 10^(12))/(2.5 * 10^4) = 3 * 10^8 which points to choice C

If you wanted to expand this out, then 3.0 becomes 300,000,000 = 300 million after moving the decimal point 8 spots to the right.

(7.5*10^(12) )/(2.5*10^(4) ) =(7.5)/(2.5) *(10^(12) )/(10^(4) ) = 3 * 10^(12 - 4) = 3*10^8

Hope that helps!
