(\sqrt{11}\left\(\sqrt{539}-\sqrt{275}\right\)) का मान क्या है?
What is the value of (\sqrt{11}\left\(\sqrt{539}-\sqrt{275}\right\))?
Explanation opens after your attempt
Correct Answer
B. (22)
Concept
\(\sqrt{539}=7\sqrt{11}\) and \(\sqrt{275}=5\sqrt{11}\), so the bracket is \(2\sqrt{11}\). Multiplying by \(\sqrt{11}\) gives (22).
Why this answer is correct
The correct answer is B. (22). \(\sqrt{539}=7\sqrt{11}\) and \(\sqrt{275}=5\sqrt{11}\), so the bracket is \(2\sqrt{11}\). Multiplying by \(\sqrt{11}\) gives (22).
Exam Tip
\(\sqrt{539}=7\sqrt{11}\) और \(\sqrt{275}=5\sqrt{11}\), इसलिए कोष्ठक \(2\sqrt{11}\) है। \(\sqrt{11}\) से गुणा करने पर (22) मिलता है।
