Respuesta:
A) 3[tex]\sqrt{2}[/tex]
B) no se puede xq 27 no tiene factor 2
C) 10 [tex]\sqrt{5}[/tex]
Explicación paso a paso:
A) [tex]5\sqrt{2 } - \sqrt{8}[/tex]
[tex]5\sqrt{2}- \sqrt{4*2}[/tex]
[tex]5\sqrt{2}-\sqrt{4}*\sqrt{2}[/tex]
[tex]5\sqrt{2}- 2\sqrt{2}[/tex]
[tex](5-2)\sqrt{2}[/tex]
[tex]3\sqrt{2}[/tex]
B) [tex]\sqrt{27} - 2\sqrt{2} \\[/tex]
[tex]\sqrt{9*3} - 2\sqrt{2}[/tex]
[tex]\sqrt{9}*\sqrt{3} - 2\sqrt{2}[/tex]
[tex]3\sqrt{3} - 2\sqrt{2}[/tex] no se puede transformar a radicales semejantes xq
27 no tiene factor 2.
C) [tex]2\sqrt{45} +2\sqrt{20}[/tex]
[tex]2\sqrt{9*5} + 2\sqrt{4*5}[/tex]
[tex]2\sqrt{9}*\sqrt{5} +2\sqrt{4} *\sqrt{5}[/tex]
[tex]2*3*\sqrt{5} + 2*2*\sqrt{5}[/tex]
[tex]6\sqrt{5} +4\sqrt{5}[/tex]
[tex](6+4)\sqrt{5}[/tex]
[tex]10\sqrt{5}[/tex]
