The correct Answer is:
To solve the given equations step by step, we will first tackle each equation separately. ### Step 1: Solve Equation I The first equation is: \[ x = (1331)^{\frac{1}{3}} \] To find the value of \( x \), we need to calculate the cube root of 1331. **Calculation:** \[ 1331 = 11^3 \] Thus, \[ x = (11^3)^{\frac{1}{3}} = 11 \] ### Step 2: Solve Equation II The second equation is: \[ 2y^2 - 17y + 36 = 0 \] This is a quadratic equation in the standard form \( ay^2 + by + c = 0 \). We can solve it using the factorization method. **Finding Factors:** We need to find two numbers that multiply to \( 2 \times 36 = 72 \) and add up to \( -17 \). The factors of 72 that satisfy this condition are \( -8 \) and \( -9 \). **Rewriting the Equation:** We can rewrite the equation as: \[ 2y^2 - 8y - 9y + 36 = 0 \] Now, we can group the terms: \[ (2y^2 - 8y) + (-9y + 36) = 0 \] Factoring by grouping: \[ 2y(y - 4) - 9(y - 4) = 0 \] Now, we can factor out \( (y - 4) \): \[ (2y - 9)(y - 4) = 0 \] **Finding Values of \( y \):** Setting each factor to zero gives us: 1. \( 2y - 9 = 0 \) → \( 2y = 9 \) → \( y = \frac{9}{2} = 4.5 \) 2. \( y - 4 = 0 \) → \( y = 4 \) ### Step 3: Summary of Solutions Now we have: - From Equation I: \( x = 11 \) - From Equation II: \( y = 4 \) and \( y = 4.5 \) ### Step 4: Compare \( x \) and \( y \) Now we compare the values of \( x \) and \( y \): - For \( y = 4 \): \( x = 11 > 4 \) - For \( y = 4.5 \): \( x = 11 > 4.5 \) In both cases, \( x \) is greater than \( y \). ### Final Answer Thus, the conclusion is: \[ x > y \] ---
