answer the question as fast as posible​

Answer 1

Answer:

Step-by-step explanation:

$\frac{3+\sqrt{6} }{2+\sqrt{5} } \\\\Multiplying \ up\ and \ down \ by \ 2-\sqrt{5} \\\\=\frac{(3+\sqrt{6})(2-\sqrt{5} ) }{(2+\sqrt{5} )(2-\sqrt{5} )}\\\\=\frac{6-3\sqrt{5}+2\sqrt{6} -\sqrt{30} }{4-5} \\\\\bf=-8+3\sqrt{5}-2\sqrt{6} +\sqrt{30}$
