The correct Answer is:
To find the absolute value of \(\left(\frac{2}{-3}\right)^{4}\), we can follow these steps: ### Step 1: Rewrite the expression We start with the expression: \[ \left(\frac{2}{-3}\right)^{4} \] This can be rewritten using the property of exponents: \[ \frac{2^{4}}{(-3)^{4}} \] ### Step 2: Calculate \(2^{4}\) Now, we calculate \(2^{4}\): \[ 2^{4} = 2 \times 2 \times 2 \times 2 = 16 \] ### Step 3: Calculate \((-3)^{4}\) Next, we calculate \((-3)^{4}\): \[ (-3)^{4} = (-3) \times (-3) \times (-3) \times (-3) \] Since multiplying two negative numbers gives a positive number: \[ (-3) \times (-3) = 9 \quad \text{and} \quad 9 \times 9 = 81 \] Thus, \((-3)^{4} = 81\). ### Step 4: Combine the results Now, we can combine the results from Steps 2 and 3: \[ \frac{2^{4}}{(-3)^{4}} = \frac{16}{81} \] ### Step 5: Find the absolute value The absolute value of a positive number is the number itself. Since \(\frac{16}{81}\) is already positive, we have: \[ \text{Absolute value} = \left|\frac{16}{81}\right| = \frac{16}{81} \] ### Final Answer Therefore, the absolute value of \(\left(\frac{2}{-3}\right)^{4}\) is: \[ \frac{16}{81} \] ---
