The correct Answer is:
To find the value of the expression \( \sqrt[3]{512} + \sqrt[4]{16} + \sqrt{576} \), we will break it down step by step. ### Step 1: Calculate \( \sqrt[3]{512} \) First, we need to find the cube root of 512. - **Prime Factorization of 512**: \[ 512 = 2^9 \quad (\text{since } 512 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2) \] - **Cube Root Calculation**: \[ \sqrt[3]{512} = \sqrt[3]{2^9} = 2^{9/3} = 2^3 = 8 \] ### Step 2: Calculate \( \sqrt[4]{16} \) Next, we find the fourth root of 16. - **Prime Factorization of 16**: \[ 16 = 2^4 \] - **Fourth Root Calculation**: \[ \sqrt[4]{16} = \sqrt[4]{2^4} = 2^{4/4} = 2^1 = 2 \] ### Step 3: Calculate \( \sqrt{576} \) Now, we will calculate the square root of 576. - **Prime Factorization of 576**: \[ 576 = 24 \times 24 = (2^3 \times 3)^2 = 2^6 \times 3^2 \] - **Square Root Calculation**: \[ \sqrt{576} = \sqrt{2^6 \times 3^2} = \sqrt{2^6} \times \sqrt{3^2} = 2^{6/2} \times 3^{2/2} = 2^3 \times 3^1 = 8 \times 3 = 24 \] ### Step 4: Combine the Results Now we add the results from the previous steps: \[ \sqrt[3]{512} + \sqrt[4]{16} + \sqrt{576} = 8 + 2 + 24 \] Calculating this gives: \[ 8 + 2 + 24 = 34 \] ### Final Answer Thus, the value of the expression is: \[ \boxed{34} \]
