Multiple choice

In each of the following questions two equations (I) and (II) are given. Solve these equations and give the answer: (I) (x^2 - 324 = 0) (II) (y = \sqrt{324})

  1. $\(x < y\)$
  2. $\(x > y\)$
  3. $\(x \ge y\)$
  4. $\(x \le y\)$
  5. $\(x = y\) or no relationship can be established between \(x\) and \(y\)$

D Correct answer
Explanation

For equation (I), x^2 - 324 = 0 gives x = ±18. For equation (II), y = √324 gives y = 18 (principal square root). When x = 18, x = y; when x = -18, x < y. In both cases, x ≤ y holds true.
