Please answer thankssss

Answer 1

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.

Answer 2

`(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!
