Answer 2

Given :

expression $1/3+\sqrt{5}$

To find :

rationalizing factor

Step-by-step explanation:

=> $\frac{1}{3+\sqrt{5} } *\frac{3-\sqrt{5} }{3-\sqrt{5} }\\ \\= \frac{3-\sqrt{5} }{(3)^2 - (\sqrt{5})^2 }\\\\= \frac{3-\sqrt{5} }{9 - 5 }\\\\\\\\= \frac{3-\sqrt{5} }{4}$

hence :

$\frac{3-\sqrt{5} }{4}$

is the correct answer
