Answer 1

Step-by-step explanation:

$\huge\sf\underline\red{answer}$

$\frac{ \sqrt{5 }+1 }{ \sqrt{5 }-2 }$

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

$\frac{ \sqrt{5}( \sqrt{5} + 2) + 1( \sqrt{5} + 2) }{5 - 4}$

$\frac{5 + 2 \sqrt{5} + \sqrt{5} + 2 }{1}$

$\frac{7 + 3 \sqrt{5} }{1}$

$7 + 3 \sqrt{5}$
