65,632.25 in expanded form is : 60,000 + 5,000 + 600 + 30 + 5 + .2 + .05
When you have multiplying with same base, you add the power, for example here : z^6 * z^3 = z^(6+3) = z^9.
When you have dividing with the same base, you substract it, for example here : z^9/z^4 = z^(9-4) = z^5.
Let's go through the answer choices one by one:
A. False. The line segment contains more than just the endpoints
B. False. There are points in this description that extend beyond the endpoints. If this was a line instead of a segment, then choice B would be the answer
C. True. This is the answer. Though your teacher should have added "collinear" to the sentence to make it clear that the points are between M and N, and also collinear to M and N. All of these points form the line segment MN
D. False. That would be the perpendicular bisector of MN

So once again, the final answer is choice C
