Describe and correct the error in the problem.
2^-4 = -2*-2*-2*-2 = 16

1. She changed the negative exponent to a negative base. The problem should be 2^-4 = 1/2^4 = 1/2*2*2*2 = 1/16.

2. She did not multiply correctly. The answer should be 16.

3. She made the answer positive. It should be -16.

4. She did not multiply by -1. The problem should be 2^-4 = (-1)1/2^4 = (-1)1/2*2*2*2 = 1/16.

Is answer #1 the correct answer?
