Question

simplify (5+root 7) (2+root5)

Answer 1

Answer:

$Product\: of\\ \: (5+\sqrt{7})(2+\sqrt{5})\\=10+5\sqrt{5}+2\sqrt{7}+\sqrt{35}$

Step-by-step explanation:

$Product\: of\\ \: (5+\sqrt{7})(2+\sqrt{5})\\=5(2+\sqrt{5})+\sqrt{7}(2+\sqrt{5})\\=10+5\sqrt{5}+2\sqrt{7}+\sqrt{7}\times \sqrt{5}\\=10+5\sqrt{5}+2\sqrt{7}+\sqrt{35}$

Therefore,

$Product\: of\\ \: (5+\sqrt{7})(2+\sqrt{5})\\=10+5\sqrt{5}+2\sqrt{7}+\sqrt{35}$
