यदि \(x=2-\sqrt{3}\), तो \(\frac{1}{x}+x\) का मान क्या है?
If \(x=2-\sqrt{3}\), what is the value of \(\frac{1}{x}+x\)?
Explanation opens after your attempt
A. (4)
Concept
Since \(\frac{1}{2-\sqrt{3}}=2+\sqrt{3}\), (\frac{1}{x}+x=\(2+\sqrt{3}\)+\(2-\sqrt{3}\)=4). In exams, identify conjugate numbers quickly.
Why this answer is correct
The correct answer is A. (4). Since \(\frac{1}{2-\sqrt{3}}=2+\sqrt{3}\), (\frac{1}{x}+x=\(2+\sqrt{3}\)+\(2-\sqrt{3}\)=4). In exams, identify conjugate numbers quickly.
Exam Tip
\(\frac{1}{2-\sqrt{3}}=2+\sqrt{3}\), इसलिए (\frac{1}{x}+x=\(2+\sqrt{3}\)+\(2-\sqrt{3}\)=4)। परीक्षा में संयुग्म संख्या तुरंत पहचानें।
