( \left\(\frac{1}{3-\sqrt{7}}\right\)+\left\(\frac{1}{3+\sqrt{7}}\right\) ) का मान क्या है?
What is the value of ( \left\(\frac{1}{3-\sqrt{7}}\right\)+\left\(\frac{1}{3+\sqrt{7}}\right\) )?
Explanation opens after your attempt
Correct Answer
A. (3)
Concept
The common denominator is (9-7=2), and the numerator is \(3+\sqrt{7}+3-\sqrt{7}=6\). So the value is \( \frac{6}{2}=3 \).
Why this answer is correct
The correct answer is A. (3). The common denominator is (9-7=2), and the numerator is \(3+\sqrt{7}+3-\sqrt{7}=6\). So the value is \( \frac{6}{2}=3 \).
Exam Tip
समान हर (9-7=2) और अंश \(3+\sqrt{7}+3-\sqrt{7}=6\) है। इसलिए मान \( \frac{6}{2}=3 \) है।
