Answer 1

$\huge{ \color{aqua}{ \underbrace{ \underline{ \color{lime}{ \mathbb{✯꧁᭄⋆SoLuTiOn⋆᭄꧂✯ }}}}}}$

$\tt \to \frac{ \sqrt{5 } + 1} { \sqrt{5} - 1 } + \frac{ \sqrt{5} - 1}{ \sqrt{5} + 1 }$

$\tt \to( \frac{ \sqrt{5} + 1 }{ \sqrt{5} - 1} \times \frac{ \sqrt{5} + 1}{ \sqrt{5} + 1} ) + ( \frac{ \sqrt{5} - 1}{ \sqrt{5} + 1 } \times \frac{ \sqrt{5} - 1}{ \sqrt{5} - 1 } )$

$\tt \to \frac{5 + 1}{5 - 1} + \frac{5 + 1}{5 - 1}$

$\tt \to \frac{6}{4} + \frac{6}{4}$

$\tt \to \frac{ \cancel{12}}{ \cancel4}$

$\tt \to3$

Answer 2

here's your answer...try to understand the concept ...here I have used the formula ( a + b ) ( a - b ) = a^2 - b^2 !!!!
