      I. x³=  ((4)5+ (15)³)/(3)4

      II. 8y³=(-13)3÷ √1521+ (3y)³  In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer.
      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 < y Correct Answer Incorrect Answer
      E If x = y or relationship between x and y cannot be established Correct Answer Incorrect Answer

      Solution

      I. x³=  ((4)5 + (15)³)/(3)4  x³=  (1024+3375)/81 = 4399/81  = 54 x³=54  x= ∛54  II. 8y³= (-13)3 ÷ √1521+ (3y)³ 8y³= -2197 ÷39 + 27y³ y³=  56/19 y= ∛(56/19)  Hence, x > y
