Question

Your friend tells you that when evaluating a powe, the answer is always negative if the base is negative. Do you agree or disagree? Explain and provide an example to support your answer.​

Answer 1

You should disagree, and as a counterexample, consider

(-2)² = (-1 × 2)² = (-1)² × 2² = 1 × 4 = 4

which is clearly positive.
