Explicație pas cu pas:
1. (7^2)/7[tex]\sqrt{7}[/tex]=[tex](7^2)/7\sqrt{7}=7/\sqrt{7} =\sqrt{7}[/tex]
2. [tex]11/11\sqrt{11} =\sqrt{11}[/tex]
3 [tex][(1/3) \sqrt{1/3}]/(1/3)^2=\sqrt{1/3}[/tex]
4 [tex]8\sqrt{8} /8^2\sqrt{8} =1/8[/tex]
5.[tex]6\sqrt{6} /6^2\sqrt{6} =1/6[/tex]
6.[tex](1/0.4)/\sqrt{(5/2)^3}=(1/0.4)/(5/2)\sqrt{5/2}\\=(5/2)/(5/2)\sqrt{5/2} =\sqrt{5/2}/5/2[/tex]
