Question

17.

Answer 1

Answer:

16. C. 7.8 * 10⁷

17. B. 0.0361

Step-by-step explanation:

#16:

Looking at the "78 million," I'll put that into a number first, which would be 78,000,000. The million already accounts for 6 zeros, so we quickly get to 78 * 10⁶. But we need for the 78 to be a decimal, so we do one more shift to the left to get 7.8 * 10⁷, which is D.

#17:

3.61 * 10⁻² means that you move the decimal point on 3.61 two spots to the left. That would become 0.0361, which is B.
