Carmen stated that the following demonstrates why the Power of Zero Rule of Exponents is equal to 1.

99=9191=91−1=90=1 .

In 1–2 sentences, say whether Carmen is correct, and explain why or why not

Carmen is incorrect. The given equation does not demonstrate the Power of Zero Rule of Exponents, which states that any nonzero number raised to the power of zero is equal to 1. The equation provided does not involve exponentiation and does not fulfill the requirements of the rule.
