Resposta:

a) \frac{5}{\sqrt{2}}  = \frac{5}{\sqrt{2}} *\frac{\sqrt{2}}{\sqrt{2}}  = \frac{5\sqrt{2}}{2}.

b) \frac{8}{\sqrt{3}} =  \frac{8}{\sqrt{3}} *\frac{\sqrt{3} }{\sqrt{3} } = \frac{8\sqrt{3} }{3}.

c) \frac{6}{\sqrt{7}} =  \frac{6}{\sqrt{7}} *\frac{\sqrt{7} }{\sqrt{7} } = \frac{6\sqrt{7} }{7}.

d) \frac{12}{\sqrt{5}} =  \frac{12}{\sqrt{5}} *\frac{\sqrt{5} }{\sqrt{5} } = \frac{12\sqrt{5} }{5}.

e) \frac{9}{\sqrt{6}} =  \frac{9}{\sqrt{6}} *\frac{\sqrt{6} }{\sqrt{6} } = \frac{9\sqrt{6} }{6}  =  \frac{9\sqrt{3} }{2}.
