Respuesta:
a) [tex]7\sqrt{5}[/tex]
b) [tex]4\sqrt{3}[/tex]
c) [tex]6\sqrt[3]{2}[/tex]
Explicación paso a paso:
La primera.
[tex]2 \sqrt{5}+\sqrt{9 . 5}+\sqrt{36 . 5}-\sqrt{16.5}\\2\sqrt{5}+3\sqrt{5}+6\sqrt{5}-4\sqrt{5}\\7\sqrt{5}[/tex]
La segunda
[tex]\sqrt{36 . 3}+\sqrt{9 . 3} - \sqrt{25 . 3}\\6\sqrt{3}+3\sqrt{3}-5\sqrt{3}\\4\sqrt{3}[/tex]
La tercera
[tex]\sqrt[3]{27.2} -\sqrt[3]{8.2}+\sqrt[3]{125.2}\\3\sqrt[3]{2}-2\sqrt[3]{2}+5\sqrt[3]{2}\\6\sqrt[3]{2}[/tex]
