Answer:

The Answer is A. 8

Explanation:

For Answer Choice A:

There's nothing to explain here. It's just the number 8.

For Answer Choice B:

2 · 2 · 2 · 2 is 16. That symbol ( · ) is another way of writing the multiplication symbol. So this problem is essentially 2 x 2 x 2 x 2, which equals 16.

For Answer Choice C:

Well, this one needs no explanation either. It's just the number 16.

For Answer Choice D:

$2^{4}$ is also equal to 16. I'm too lazy to explain how to do this one so yea.
