( \left\(\frac{1}{\sqrt{7}-\sqrt{6}}\right\)-\left\(\frac{1}{\sqrt{7}+\sqrt{6}}\right\) ) का मान क्या है?
What is the value of ( \left\(\frac{1}{\sqrt{7}-\sqrt{6}}\right\)-\left\(\frac{1}{\sqrt{7}+\sqrt{6}}\right\) )?
Explanation opens after your attempt
Correct Answer
A. \(2\sqrt{6}\)
Concept
The common denominator is (7-6=1), and the numerator is ( \sqrt{7}+\sqrt{6}-\(\sqrt{7}-\sqrt{6}\)=2\sqrt{6} ).
Why this answer is correct
The correct answer is A. \(2\sqrt{6}\). The common denominator is (7-6=1), and the numerator is ( \sqrt{7}+\sqrt{6}-\(\sqrt{7}-\sqrt{6}\)=2\sqrt{6} ).
Exam Tip
समान हर (7-6=1) और अंश ( \sqrt{7}+\sqrt{6}-\(\sqrt{7}-\sqrt{6}\)=2\sqrt{6} ) है।
