Resposta :

[tex]\frac{4}{\sqrt{2} }+\frac{9}{\sqrt{3} } =[/tex]

[tex]\frac{\sqrt{16} }{\sqrt{2} }+\frac{\sqrt{81} }{\sqrt{3} }=[/tex]

[tex]\frac{\sqrt{8.2} }{\sqrt{2} }+\frac{\sqrt{27.3} }{\sqrt{3} }=[/tex]

[tex]\frac{\sqrt{8}.\sqrt{2} }{\sqrt{2} }+\frac{\sqrt{27}.\sqrt{3}}{\sqrt{3}}=[/tex]

[tex]\sqrt{8}+\sqrt{27}=[/tex]

[tex]\sqrt{4.2}+\sqrt{9.3}=[/tex]

[tex]2\sqrt{2}+3\sqrt{3}[/tex]
