( \sqrt{18}\(2\sqrt{8}-\sqrt{50}\) ) का मान क्या है?
What is the value of ( \sqrt{18}\(2\sqrt{8}-\sqrt{50}\) )?
Explanation opens after your attempt
Correct Answer
B. ( -6 )
Concept
\(2\sqrt{8}=4\sqrt{2}\) and \( \sqrt{50}=5\sqrt{2} \), so the bracket is \( -\sqrt{2} \). ( \sqrt{18}\times\(-\sqrt{2}\)=-\sqrt{36}=-6 ).
Why this answer is correct
The correct answer is B. ( -6 ). \(2\sqrt{8}=4\sqrt{2}\) and \( \sqrt{50}=5\sqrt{2} \), so the bracket is \( -\sqrt{2} \). ( \sqrt{18}\times\(-\sqrt{2}\)=-\sqrt{36}=-6 ).
Exam Tip
\(2\sqrt{8}=4\sqrt{2}\) और \( \sqrt{50}=5\sqrt{2} \), इसलिए कोष्ठक \( -\sqrt{2} \) है। ( \sqrt{18}\times\(-\sqrt{2}\)=-\sqrt{36}=-6 )।
