Explanation:
Given the quotient:
![(6*10^8)/(1.5*10^(-4))](https://img.qammunity.org/2021/formulas/mathematics/college/ateaa5o86kkvl7vkspcyqgpadm17u45hqg.png)
To evaluate, we first separate the given expression as follows.
![=(6)/(1.5)X(10^8)/(10^(-4))](https://img.qammunity.org/2021/formulas/mathematics/college/m1c15k90oypvrpyxkroiea6ptlevog474j.png)
Next, we apply the division law of indices to the powers of 10.
Division Law of Indices:
![(a^x)/(a^y)=a^(x-y)](https://img.qammunity.org/2021/formulas/mathematics/college/7o9lhbwujzn7m2uaffm5zin6m5m6fw7l71.png)
![=4X10^(8-(-4))\\=4X10^(8+4)\\=4X10^(12)](https://img.qammunity.org/2021/formulas/mathematics/college/d73hh5wfy1iu9wp3vwtb9m52l1o5uuwgl5.png)
Therefore, our quotient is
.
The correct answer is A.
