The correct Answer is:
To solve the question \( x = \sqrt[3]{\frac{13 \cdot 103}{125}} \), we will follow these steps: ### Step 1: Calculate the product in the numerator First, we need to calculate \( 13 \cdot 103 \). \[ 13 \cdot 103 = 1339 \] ### Step 2: Rewrite the expression Now we can rewrite \( x \) as follows: \[ x = \sqrt[3]{\frac{1339}{125}} \] ### Step 3: Simplify the cube root We know that \( 125 = 5^3 \), so we can rewrite the expression: \[ x = \sqrt[3]{\frac{1339}{5^3}} = \frac{\sqrt[3]{1339}}{\sqrt[3]{125}} = \frac{\sqrt[3]{1339}}{5} \] ### Step 4: Calculate the cube root of 1339 Since \( 1339 \) is not a perfect cube, we can approximate its cube root. However, for simplicity, we will keep it as \( \sqrt[3]{1339} \). ### Step 5: Final expression for x Thus, we have: \[ x = \frac{\sqrt[3]{1339}}{5} \] ### Step 6: Approximate the value of \( \sqrt[3]{1339} \) To find the approximate value of \( \sqrt[3]{1339} \), we can use a calculator or estimation techniques. The approximate value is around \( 10.9 \). Now substituting back: \[ x \approx \frac{10.9}{5} \approx 2.18 \] ### Final Answer So, the value of \( x \) is approximately \( 2.18 \). ---
