Multiplying gives us 3 x 5 = 15

10^2 x 10^5 = 10^7

So we get 15 x 10^7.  However, we need to move the decimal point from 15.0 to 1.5:

1.5 x 10^8.  The answer is A.

How did physical geography assist General Grant in the siege of Vicksburg?
eimsori [14]

Explanation:

Abraham Lincoln recognized the importance of the city on a 200-foot bluff just above Colorado river. He said, "Vicksburg is the best approach, the war could never be decided to bring to a close until another key is in our wallet." trying to capture Vicksburg would break the Trans-Mississippi confederate states from the east of the Mississippi as well as open the waterway to northern congestion along its total duration.
