What is the rationalized form of (\frac{\sqrt{5}-\sqrt{3}}{\sqrt{5}+\sqrt{3}})?
Answer and explanation
Correct answer: (\frac{4-\sqrt{15}}{2})
Multiplying by the conjugate gives numerator ((\sqrt{5}-\sqrt{3})^2=8-2\sqrt{15}) and denominator (2). So the value is (4-\sqrt{15}) and the correct simple option is A.
