Amy, Lin, and Miguel were practicing creating equivalent expression for (153)9.

Amy got an expression of 1527,
Miguel got an expression of 1512,
and Lin got an expression of 153.

To determine who correctly used the Power Rule of Exponents to create an equivalent expression for \((153)^9\), let's evaluate the given expressions against the original expression.

  1. Power Rule of Exponents: The Power Rule states that \((a^m)^n = a^{m \cdot n}\). So when we have an expression such as \((153)^9\), it stays as it is, but we need to check if any conversions to numerical values match correctly.

  2. Evaluating Amy's Expression:

    • Amy wrote \(1527\).
    • \(153^9\) is significantly larger than \(1527\).
  3. Evaluating Lin's Expression:

    • Lin wrote \(153\).
    • This does not represent \((153)^9\), but rather just \(153\) itself, so it is not equivalent.
  4. Evaluating Miguel's Expression:

    • Miguel wrote \(1512\).
    • Similar to Amy's case, \(153^9\) is much larger than \(1512\).

Based on this analysis:

  • Amy's and Miguel's expressions are all incorrect in that they do not equate to \((153)^9\).
  • Lin's expression \(153\) also does not represent an equivalent expression for \((153)^9\), but is just a numerical representation of the base.

Therefore, none of them correctly expressed \((153)^9\) using the Power Rule of Exponents. All of them made mistakes, and the correct equivalent expression should have remained as \((153)^9\) or evaluated correctly without losing the exponent.

The answer is that none of them correctly used the Power Rule of Exponents.
