Answer 1

Hey bro here is your answer:

$(\sqrt{2}+\sqrt{3})(\sqrt{5}+\sqrt{7})\\\ \sqrt{2}(\sqrt{5}+\sqrt{7})+\sqrt{3}(\sqrt{5}+\sqrt{7})\\\sqrt{10}+\sqrt{14}+\sqrt{15}+\sqrt{21}$

Pls mark as brainliest........

Step-by-step explanation:

Answer 2

$\huge{\underline{\red{\mathfrak{AnSwEr}}}}$

$( \sqrt{2} + \sqrt{3} )( \sqrt{5} + \sqrt{7} ) \\ = \sqrt{2} ( \sqrt{5} + \sqrt{7} ) + \sqrt{3} ( \sqrt{5} + \sqrt{7} ) \\ = \sqrt{10} + \sqrt{14} + \sqrt{15} + \sqrt{21}$
