(\sqrt{2}\left\(\sqrt{50}-\sqrt{18}\right\)) का मान क्या है?
What is the value of (\sqrt{2}\left\(\sqrt{50}-\sqrt{18}\right\))?
Explanation opens after your attempt
Correct Answer
A. (4)
Concept
\(\sqrt{50}=5\sqrt{2}\) and \(\sqrt{18}=3\sqrt{2}\), so the bracket is \(2\sqrt{2}\). Multiplying by \(\sqrt{2}\) gives (4).
Why this answer is correct
The correct answer is A. (4). \(\sqrt{50}=5\sqrt{2}\) and \(\sqrt{18}=3\sqrt{2}\), so the bracket is \(2\sqrt{2}\). Multiplying by \(\sqrt{2}\) gives (4).
Exam Tip
\(\sqrt{50}=5\sqrt{2}\) और \(\sqrt{18}=3\sqrt{2}\), इसलिए कोष्ठक \(2\sqrt{2}\) है। \(\sqrt{2}\) से गुणा करने पर (4) मिलता है।
