Answer:

Explanation:

Adding the expressions in the numerator, we get:

6·10^(-5).

Then the given fraction appears like:

6·10^(-5)

-------------

3·10^7

First, we reduce 6/3, obtaining 2:

10^(-5)

2 -------------

10^(7)

Since the bases are the same, we can rewrite these exponentials with that base (10) and single exponent 12, which is the sum of 5 and 7 and is in the denominator:

2

---------

10^12

This matches the second possible answer choice.
