Respostas:
I. 1,1547
II. 2,12132
III. 1,78885
IV. [tex]\frac{5}{2}[/tex]
Explicação passo a passo:
I.
[tex]\frac{2}{\sqrt{3}} \\\frac{2}{\sqrt{3}} * \frac{\sqrt{3} }{\sqrt{3} } \\\frac{2\sqrt{3} }{\sqrt{3} \sqrt{3} } \\\frac{2\sqrt{3} }{3} \\Forma\\alternativa=1,1547[/tex]
II.
[tex]\frac{3}{\sqrt{2} } \\\frac{3}{\sqrt{2} } *\frac{\sqrt{2} }{\sqrt{2} } \\\frac{3\sqrt{2} }{\sqrt{2} \sqrt{2} } \\\frac{3\sqrt{2} }{2} \\Forma\\alternativa=2,12132[/tex]
III.
[tex]\frac{4}{\sqrt{5} } \\\frac{4}{\sqrt{5} } *\frac{\sqrt{5} }{\sqrt{5} } \\\frac{4\sqrt{5} }{\sqrt{5} \sqrt{5} } \\\frac{4\sqrt{5} }{5} \\Forma\\alternativa=1,78885[/tex]
IV.
[tex]\frac{5}{\sqrt{4} } \\\frac{5}{\sqrt{2^{2} } } \\\frac{5}{2}[/tex]
espero ter ajudado! :)
