Question

Please answer thankssss

Answer 1

$\frac{7.5*10^{12} }{2.5*10^{4} } =\frac{7.5}{2.5} *\frac{10^{12} }{10^{4} } = 3 * 10^{12 - 4} = 3*10^8$

Hope that helps!

Answer 2

Answer: Choice C

$3 \times 10^8$

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

Explanation:

Divide 7.5 over 2.5 to get 3

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

$\frac{a^b}{a^c} = a^{b-c}$

So,

$\frac{10^{12}}{10^4} = 10^{12-4} = 10^8$

Overall,

$\frac{7.5 \times 10^{12}}{2.5 \times 10^4} = 3 \times 10^8$ 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.
