    Answer:

      36\sqrt{2}+30\sqrt{3}+10\sqrt{14}+8\sqrt{21}

    Step-by-step explanation:

    Use the distributive property and the rules of roots.

      (2\sqrt{7}+3\sqrt{6})(5\sqrt{2}+4\sqrt{3}) = 10\sqrt{14}+8\sqrt{21}+15\sqrt{12}+12\sqrt{18}\\\\=\boxed{36\sqrt{2}+30\sqrt{3}+10\sqrt{14}+8\sqrt{21}}

    (a√b)(c√d) = (ac)√(bd)

    √(a²b) = a√b
