The correct Answer is:
To solve the expression \( A^{2/3} \times A^{3/2} \times A^{1/2} \), we will follow these steps: ### Step 1: Write the expression We start with the expression: \[ A^{2/3} \times A^{3/2} \times A^{1/2} \] ### Step 2: Use the property of exponents Since the bases are the same (all are \( A \)), we can add the exponents together: \[ A^{(2/3) + (3/2) + (1/2)} \] ### Step 3: Find a common denominator To add the fractions, we need to find a common denominator. The denominators are 3, 2, and 2. The least common multiple (LCM) of these numbers is 6. ### Step 4: Convert each fraction to have the common denominator Now we convert each fraction: - \( \frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4}{6} \) - \( \frac{3}{2} = \frac{3 \times 3}{2 \times 3} = \frac{9}{6} \) - \( \frac{1}{2} = \frac{1 \times 3}{2 \times 3} = \frac{3}{6} \) ### Step 5: Add the fractions Now we can add the fractions: \[ \frac{4}{6} + \frac{9}{6} + \frac{3}{6} = \frac{4 + 9 + 3}{6} = \frac{16}{6} \] ### Step 6: Simplify the fraction Next, we simplify \( \frac{16}{6} \): \[ \frac{16}{6} = \frac{8}{3} \] ### Step 7: Write the final expression Thus, we have: \[ A^{(8/3)} \] ### Final Answer The final answer is: \[ A^{8/3} \] ---
