यदि \(a=3\sqrt{2}+4\) और \(b=3\sqrt{2}-4\) हैं तो (a+b) क्या है?
If \(a=3\sqrt{2}+4\) and \(b=3\sqrt{2}-4\), what is (a+b)?
Explanation opens after your attempt
Correct Answer
B. \(6\sqrt{2}\)
Concept
The constant terms cancel and \(3\sqrt{2}+3\sqrt{2}=6\sqrt{2}\). Add like radicals.
Why this answer is correct
The correct answer is B. \(6\sqrt{2}\). The constant terms cancel and \(3\sqrt{2}+3\sqrt{2}=6\sqrt{2}\). Add like radicals.
Exam Tip
स्थिर पद कट जाते हैं और \(3\sqrt{2}+3\sqrt{2}=6\sqrt{2}\) मिलता है। समान मूलों को जोड़ें।
