Let's analyze the steps Jamie applied to evaluate the expression:

### Step 1:
**Expression:** \(\frac{[(2^3)(2)]^4}{2^{10}}\)

- **Transformation:** Jamie rewrote it as \(\frac{(2^4)^4}{2^{10}}\).

**Rule Applied:** This step involves the **Product of Powers Rule**, which states that when you multiply two expressions with the same base, you add their exponents. In the original expression, \( (2^3)(2) \) simplifies to \( 2^{3+1} = 2^4 \).

### Step 2:
**Expression:** \(\frac{(2^4)^4}{2^{10}}\)

- **Transformation:** Jamie simplified \((2^4)^4\) to \(2^{16}\).

**Rule Applied:** This step uses the **Power of a Power Rule**, which states that when you raise a power to another power, you multiply the exponents: \( (a^m)^n = a^{m \cdot n} \).

### Step 3:
**Expression:** \(\frac{2^{16}}{2^{10}}\)

- **Transformation:** Jamie simplified the fraction to \(2^{16 - 10}\).

**Rule Applied:** This step applies the **Quotient of Powers Rule**, which states that when you divide two expressions with the same base, you subtract the exponents: \(\frac{a^m}{a^n} = a^{m-n}\).

### Summary of Rules Applied:
- **Step 1:** Product of Powers Rule
- **Step 2:** Power of a Power Rule
- **Step 3:** Quotient of Powers Rule

**Final Answer:** Jamie made a computational error in Step 3. The correct computation would yield \(2^6\), which equals \(64\), confirming that Step 4 is correct.
