Răspuns pas cu pas:

a) $\frac{5}{\sqrt{5}} *\frac{\sqrt{5}}{\sqrt{5}} = \frac{5\sqrt{5}}{5} = \sqrt{5}$

b) $\frac{1}{\sqrt{3}} * \frac{\sqrt{3}}{\sqrt{3}} = \frac{\sqrt{3}}{3}$

c) $\frac{6}{5\sqrt{2}} *\frac{\sqrt{2}}{\sqrt{2}} = \frac{6\sqrt{2}}{5*2}= \frac{3\sqrt{2}}{5}$

d) $\frac{5}{4\sqrt{3}} * \frac{\sqrt{3}}{\sqrt{3}} = \frac{5\sqrt{3}}{4*3} = \frac{5\sqrt{3}}{12}$
