The correct Answer is:
To calculate the total number of prime factors in the expression \( (9)^{11} \times (5)^{7} \times (7)^{5} \times (3) \times (2) \times (17)^{2} \), we will follow these steps: ### Step 1: Rewrite the expression with prime bases First, we need to express all numbers in the expression using their prime factors. - \( 9 = 3^2 \), so \( (9)^{11} = (3^2)^{11} = 3^{22} \). Now, we can rewrite the entire expression: \[ (3^{22}) \times (5^{7}) \times (7^{5}) \times (3^{1}) \times (2^{1}) \times (17^{2}) \] ### Step 2: Combine like bases Next, we combine the powers of the same base. - For base \( 3 \): \( 3^{22} \times 3^{1} = 3^{22 + 1} = 3^{23} \). Now the expression becomes: \[ 3^{23} \times 5^{7} \times 7^{5} \times 2^{1} \times 17^{2} \] ### Step 3: Identify the prime factors and their powers Now we list the prime factors and their respective powers: - \( 3^{23} \) - \( 5^{7} \) - \( 7^{5} \) - \( 2^{1} \) - \( 17^{2} \) ### Step 4: Calculate the total number of prime factors To find the total number of prime factors, we add the powers of each prime factor: - The power of \( 3 \) is \( 23 \). - The power of \( 5 \) is \( 7 \). - The power of \( 7 \) is \( 5 \). - The power of \( 2 \) is \( 1 \). - The power of \( 17 \) is \( 2 \). Now, we calculate: \[ 23 + 7 + 5 + 1 + 2 = 38 \] ### Final Answer The total number of prime factors in the expression is \( 38 \).
