Question

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.

(2 points)

Carmen is incorrect. The Power of Zero Rule of Exponents states that any non-zero number raised to the power of zero is equal to 1, not any number. In the demonstration provided by Carmen, the number 9 is being raised to the power of zero, not a non-zero number.
