यदि सार्वत्रिक समुच्चय \(U=\mathbb{R}\) और \(A={x:x^2=4}\) है, तो (A') क्या दर्शाता है?
If the universal set is \(U=\mathbb{R}\) and \(A={x:x^2=4}\), what does (A') represent?
Explanation opens after your attempt
Correct Answer
A. सभी वास्तविक संख्याएँ सिवाय (-2) और (2)All real numbers except (-2) and (2)
Concept
The solutions of \(x^2=4\) are (-2) and (2). In \(\mathbb{R}\), the complement is all real numbers except these two.
Why this answer is correct
The correct answer is A. सभी वास्तविक संख्याएँ सिवाय (-2) और (2) / All real numbers except (-2) and (2). The solutions of \(x^2=4\) are (-2) and (2). In \(\mathbb{R}\), the complement is all real numbers except these two.
Exam Tip
\(x^2=4\) के हल (-2) और (2) हैं। \(\mathbb{R}\) में पूरक इन दोनों को छोड़कर सभी वास्तविक संख्याएँ हैं।
