Answer 2

$Value \: of \: \frac{4}{\sqrt{5} + \sqrt{3}}$

$= \frac{4(\sqrt{5} - \sqrt{3})}{(\sqrt{5} + \sqrt{3})(\sqrt{5} - \sqrt{3})} \\= \frac{4(\sqrt{5} - \sqrt{3})}{(\sqrt{5})^{2} -( \sqrt{3})^{2}} \\= \frac{4(\sqrt{5} - \sqrt{3})}{(5 - 3 } \\= \frac{4(\sqrt{5} - \sqrt{3})}{2 } \\= 2(\sqrt{5} - \sqrt{3})\\ = 2 ( 2.236 - 1.732 ) \\= 2 \times 0.504 \\=1.008$

Therefore.,

$\red{Value \: of \: \frac{4}{\sqrt{5} + \sqrt{3}}}\green { = 1.008}$
