    Question

    I. (x13/5 ÷7) = 5488 ÷

    x7/5 II. (y2/3 × y2/3 ) ÷ √4 = (343y)1/3
    A If x ≥y Correct Answer Incorrect Answer
    B If x ≤y Correct Answer Incorrect Answer
    C If x>y Correct Answer Incorrect Answer
    D If x Correct Answer Incorrect Answer
    E If x=y or relationship between x and y cannot be established Correct Answer Incorrect Answer

    Solution

    I. (x(13/5) ÷7) = 5488 ÷ x(7/5) x(13/5 + 7/5) = 5488 ×7 x4 = 38416 x = ± 14 II. {(y)(2/3) × y(2/3)} ÷ √4 = (343y)(1/3) y(4/3) ÷ y(1/3) = 2 × 7 y=14 Hence, y ≥ x
