यदि \(p=2+\sqrt{3}\) है तो \(\frac{1}{p}\) किसके बराबर है?
If \(p=2+\sqrt{3}\), what is \(\frac{1}{p}\) equal to?
Explanation opens after your attempt
Correct Answer
A. \(2-\sqrt{3}\)
Concept
Since (\(2+\sqrt{3}\)\(2-\sqrt{3}\)=1), the reciprocal is \(2-\sqrt{3}\). Recognizing conjugates is a fast method.
Why this answer is correct
The correct answer is A. \(2-\sqrt{3}\). Since (\(2+\sqrt{3}\)\(2-\sqrt{3}\)=1), the reciprocal is \(2-\sqrt{3}\). Recognizing conjugates is a fast method.
Exam Tip
क्योंकि (\(2+\sqrt{3}\)\(2-\sqrt{3}\)=1), इसलिए व्युत्क्रम \(2-\sqrt{3}\) है। संयुग्मी को पहचानना तेज तरीका है।
