Question: 163
10. 
= ?
- A. 1.6 × 1012
- B. 1.6 × 108
- C. 1.6 × 107
- D. 1.6 × 104
Correct Answer: B
Explanation:
The answer is B
. When dividing exponential terms with like bases, subtract the exponents. 
= 108, and the final simplified form equals 1.6 × 108.
All of the answer choices contain 1.6, so it is not necessary to solve that value, although you do need to determine whether the result will require moving the decimal to maintain scientific notation. If you see that the result will maintain scientific notation, all you need to do is focus on the exponent.
