Answer 2

Express in a+ |b form:

Step-by-step explanation:

$\ Given \ value:\\\\\frac{\sqrt{5}+\sqrt{3}}{\sqrt{5}-\sqrt{3}}\\\\\ Solution:\\\\\frac{\sqrt{5}+\sqrt{3}}{\sqrt{5}-\sqrt{3}} \times \frac{\sqrt{5}+\sqrt{3}}{\sqrt{5}+\sqrt{3}}\\\\\rightarrow \frac{(\sqrt{5}+\sqrt{3})^2}{(\sqrt{5})^2-(\sqrt{3})^2}\\\\\rightarrow \frac{(5+3+2\sqrt{5}\sqrt{3})}{(5-3)}\\\\\rightarrow \frac{(8+2\sqrt{5}\sqrt{3})}{(2)}\\\\\rightarrow \frac{2(4+\sqrt{5}\sqrt{3})}{2}\\\\\rightarrow (4+\sqrt{5}\sqrt{3})\\\\\rightarrow (4+\sqrt{15})$
