Answer» Answer: (5+ 7
)(2+ 5
) =10+5 5
+2 7
+ 35
Step-by-step explanation: \BEGIN{GATHERED}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}\end{gathered} Productof (5+ 7
)(2+ 5
) =5(2+ 5
)+ 7
(2+ 5
) =10+5 5
+2 7
+ 7
× 5
=10+5 5
+2 7
+ 35
