Which option is the simplified form of \(\frac{2}{\sqrt{7}-\sqrt{3}}\)?
Explanation opens after your attempt
Correct Answer
A. \(\frac{\sqrt{7}+\sqrt{3}}{2}\)
Concept
Multiplying by the conjugate makes the denominator (7-3=4). Hence we get (\frac{2\(\sqrt{7}+\sqrt{3}\)}{4}).
Why this answer is correct
The correct answer is A. \(\frac{\sqrt{7}+\sqrt{3}}{2}\). Multiplying by the conjugate makes the denominator (7-3=4). Hence we get (\frac{2\(\sqrt{7}+\sqrt{3}\)}{4}).
