Answer 1

Answer:

I think 1/5 is the answer ☺️☺️

Answer 2

Hola mate here is your answer!

Solution:

$\frac{1}{5 + 3 \sqrt{3} \times } \times \frac{1}{5 - 3 \sqrt{3 } } = \frac{1}{25 - 27}$

$= \frac{ - 1}{2}$

(x+y) =

$\frac{1}{5 + 3 \sqrt{3} } + \frac{1}{5 - 3 \sqrt{3} }$

$= \frac{5 + 3 \sqrt{3} + 5 - 3 \sqrt{3} }{ - 2}$

$= \frac{10}{ - 2}$

$= - 5$

So we get

$\frac{ - 1}{2} \times - 5$

$= \frac{5}{2}$

Option D is correct
