Question:
<p>Which of the following is not true?</p><p>(a) \(J \cup K = 3\)</p><p>(b) \(JK = 12/5\)</p><p>(c) \(|J - K| = 3/5\)</p><p>(d) \(|J| + |K| = 2\sqrt{3}/5\)</p>
<p>(a) \(J \cup K = 3\)</p>
<p>(b) \(JK = 12/5\)</p>
<p>(c) \(|J - K| = 3/5\)</p>
<p>(d) \(|J| + |K| = 2\sqrt{3}/5\)</p>
Step-by-Step Solution
Key Concept: Verify each statement about complex numbers J and K to identify which is false.
<p><strong>Solution:</strong> From the given conditions and calculations, option (d) is not true.</p>
Correct Answer: D
