यदि \(a=2\sqrt{3}+1\) और \(b=2\sqrt{3}-1\) हैं तो (a+b) क्या है?
If \(a=2\sqrt{3}+1\) and \(b=2\sqrt{3}-1\), what is (a+b)?
Explanation opens after your attempt
B. \(4\sqrt{3}\)
Concept
The constant terms cancel and \(2\sqrt{3}+2\sqrt{3}=4\sqrt{3}\). Add like radicals.
Why this answer is correct
The correct answer is B. \(4\sqrt{3}\). The constant terms cancel and \(2\sqrt{3}+2\sqrt{3}=4\sqrt{3}\). Add like radicals.
Exam Tip
स्थिर पद कट जाते हैं और \(2\sqrt{3}+2\sqrt{3}=4\sqrt{3}\) मिलता है। समान मूलों को जोड़ें।
